The Boss Extreme Walkthrough

Boss Extreme Walkthrough
This is from the Metal Gear Solid 4 Walkthrough page

READ ME!!!!!!!!!!
I only thought of this after I got the Big Boss Emblem but before you go for the emblem, do a playthrough on Liquid Easy and at the end in the Missile Hangar, make sure you have 50 bullets in each of these:- The emotion bullets have the same effect as a normal anest. round (Headshot = Instant knock - out) and 50 is the maximum amout of anest. or emotion bullets on The Boss Extreme.
 * Anest. 22.
 * Laugh 22.
 * Cry 22.
 * Scream 22.
 * Rage 22.
 * Anest 7.62mm

Criteria
For the Big Boss Emblem you will need to achieve each of the following
 * Complete the game in less than 5 hours
 * Use no continues
 * Use no health items e.g. rations, regain, etc.
 * Kill no enemies (You can kill bosses including Vamp but not the beauties)
 * No alert phases (cautions are allowed)
 * No special items (stealth, bandana)
 * Complete the game on The Boss Extreme

Rewards
Upon fulfilling these criteria, you will have automatically unlocked all of these emblems for definite:-

You may have earned these too without even trying:-

You will have earned yourself the Desert Eagle w. Long Barrel , which is awesome! as well as the Patriot, even more awesome!!! Also you will unlock the Big Boss Face Camo. You will unlock Stealth Camo if you haven't already bought it because you won't have been seen. The Bandana will also be unlocked because you won't have killed anybody. Essentially, you will earn 10 million Drebin Points worth of items!!!!

Ground Zero
Don't bother with the ration under the truck, we won't be using any anyway. Just head straight to the truck on the left and crawl under. After the cutscene make sure you take the left route. When the GEKKOs arrive, stick to the left side of the street, once you pass the first GEKKO stick to the right until you leave the area.

Red Zone NW Sector
Once you arrive on the large street, take an immediate right into a little room. There should be a box, and next to it a can, run into the can, pause for just 1 second then continue, if you did it right, the 2 guards will go to where the sound was and you can carry on (this also prevents the tank cutscene). Leave the room through the doorway and don't stop running. Stick to the right of the street, past the tank until you reach a destroyed vehicle. This is where you need to make a decision, for the quick way, turn right and shoot the barrel ahead of you, it can be quite hard to see. Both PMC's in the area will now be scared run down the middle passage, you can even run into the PMC and at the end, take a right and leave the area, for this to work you need to be as fast as possible, listen out for the alert sound when you leave because, reinforcements will be coming from there, that's why you need to be quick. For the easy way, you still turn right but instead stun knife the PMC's, go down the middle passage and turn right making sure you aren't seen.

Red Zone part 1
Don't go up the steps, instead run straight to the right and stand behind the two stacked boxes, if you look to the right there is a PMC. Wait until he turns away and then wait another second. Run ahead and as soon as the archways start on your right, go inside them, very slowly crouch towards the ladder, you may need to lie down, it just depends on the timing. When you climb the ladder, lie down and move forwards for 4 seconds, then it is safe to stand and run, at the end drop off and start crouching. slowly go around the corner and stun knife the PMC that’s in your way, wait until the other sets off and you then need to time your run right, you need to avoid being heard by the PMC who just set off and avoid being seen by the PMC's ahead and behind you.

Red Zone part 2
Don’t forget you will have face camo available from now on. Equip the Militia Disguise, I don’t know if this applies to you but I think that having NV (Night Vision) turned on really helps headshots, anyway tranq. the three PMC’s. Continue staying reasonably close to the barriers, you won’t be seen at the big gap. Stick to the right hand wall and enter the opening, crouch to avoid being seen and continue to the other side. Enter the Militia Safe House

Militia Safe House
Just run through as fast as you can, after all you have the Militia Disguise, near the start there are three dead ends, one of which has tranq. ammo, make sure you get it, never miss out on an opportunity. Give away ration to the Militia to keep them extra friendly.

Urban Ruins
Just don’t waste your time picking things up and get through as quickly as you can.

Downtown
Head forward and take the first right, follow the alleyway, at the end there should be some militia. When you get to the point where Otacon mentions there being snipers, take a left and keep looking right until you see a very narrow space between two walls, wall press and get to the other side turn right twice then left. You will know if you are quick because if you are you will see a tank passing, it’s OK if you don’t though. You should see a large street ahead of you but go behind the bunch of 4 boxes and turn left immediately, where you will see another 2 next to a doorway. Go through the doorway, past the stairs, turn left and then out of the window. Turn right and then look left where you will see a vehicle, get behind it then once the first guard is at the left side of the van you crouch to the right slowly advance towards the front while being careful not to alert the second guard who will soon follow the first. Now there should be three bits of wall that stick out the third will have a vase near it. Take cover behind the second one to avoid being seen by the soon to arrive guards. They will move to your left and stop for a while, once they have gone move forward to what is now you right, and turn the corner. Stick to the right whilst crouching using the first vehicle as cover, keep moving until you come across a crawlspace. go through and when you come out you should be with some Militia. Move forwards crouching and turn the corner where the boxes are, make sure you stick to the boxes to avoid being seen. Enter through the door.

Advent Palace
Just make sure you get rid of all traps before you get to the bar. If you know you aren't in a rush for time collect them by lying on them oor by using the Metal Gear Mk.2

Advent Palace, Escape
Before anything, DON'T SHOOT ANY FROGS CLINGING TO A WALL OR CEILING Equip octocamo and facecamo as well as Mk.2 with night vision on the solid eye,. If you have the solar gun it will be useful because we don't want to use too much tranq. ammo. In case you don't have it I won't use it. Lie down in front of the Rat Patrol but not outside. You should only use 3 tranq. bullets on this first part, two for the ones on the roof and one so you don't get shot at forever because the stupid team your with can't aim and kill the FROGS. Also Because your solid eye tells you how much health an enemy has, you can shoot them either the operator in the leg or arm to damage them slightly and help out while not killing them. Once the FROGS are dealt with dont follow the team but look left to find a crawlspace. Enter it and ignore all of Otacon's comments, after all what does a super intelligent clever computer programmer scientisty person know??? When you reach the noodles take a right and have a stun grenade at hand with a smoke grenade in your inventory continue until you reach a hole in the floor throw a stun grenade down first followed by a smoke grenade, RAT Patrol should kill most of them but you may have to tranq one or two. Once you are sure there aren't any FROGS below you, drop down and find the kitchen, tranq. any frogs in there and the look to the right of where you entered, go through this door and make an immediate right, lie down (you should be next to an elevator) and release the Metal Gear Mk.2 (this is also an opportunity for you to recover your health). Look at your map on the pause menu, take the MG Mk.2 around where there are 2 blocked paths and clear all of the FROGS. You will want to go back to the kitchen now unless you want to be attacked by 5 FROGS, to take care of these with great ease and save a bit of time, plant a S.G. (Sleep Gas) Mine in front of the elevator before you leave. The area you were just in should now be clear. Go and then tranq. the 3 FROGS who will come into the kitchen. Follow the group down the stairs turn right and continue to the bathroom, take a break here and recover any lost health (make sure you are in the one with a hole in the wall. When the other bathroom wall explodes and Akiba/Johnny is knocked out throw a stun and smoke grenade through the hole. Wake Akiba when you are safe. Just watch out here, your team can't die here die here (unless you help to kill them), even if you don't help so just focus on keeping yourself alive! When you get down the hole and into the next fight it's just best to stay out of it and let the team do the work if you don't feel confident. Get the stun grenades straight after you drop down aswell. In one of the rooms you will find a nice helping of tranq. ammo. When finished, jump down the shaft and SAVE!!!!!!

Advent Palace, Garage
Collect the FROG doll if you didn't get it in the first playthrough, it's one of the 5 items needed for the all powerful Solar Gun.

Crescent Meridian
Run to the opening on the right (after the tank scene) crawl all the way to the crawlspace and then through turn left at the end the right and stick to the wall, keep going, once you get to the end of where there is a change of terrain height stand and run while staying to the right. On your left there will be some PMC's behind sandbags, just before you are in line with them, crouch, not so far behind them is a ladder which is where you are headed, keep going until you are in line with the ladder then approach and climb, follow the route until you reach a cutscene.

Millenium Park
You may want to save at the start of this area, you will need to get some difficult headshots. Ignore all the weapons and continue until you can see both the PMC's, tranq. them. If you look to the left of the burning car you will see some boxes, while crouching, run towards them, the lone PMC should see you and then pause, while he is headed in your direction(or when he stops), tranq. him. Slowly look around the corner and tranq. the PMC against the wall, NV helps. Next target the PMC on the turret, again try and use NV. Take out the 3 PMC's around the fountain any way you like, the way you do this will depend on how quickly you take out the first lot. Once they are dealt with, use the Mosin Nagant to take out the PMC in the tower. Hide, behind the boxes at the right of the entrance to the new area, tranq. the PMC to the right of the boxes, move straight right and at the end of the tent look left and tranq. the PMC. Slowly make your way to the door. Note - following this your time should be around 45 minutes (I was at 32 minutes)

Cove Valley Village
Crawl along the edge of the cliff where you start but not too far that you are seen. Take everyone out (not the rebels) and as soon as you have, drop down, get ready to stun knife the PMC who is about to come out of the door ahead on the left. Look at the right side of your map on the pause menu and take the top route (under the steps of the most North East building are some smoke grenades). Turn NV on and you will see a guard walking away creep up on him, tranq. him or get to the same height and use the Mk.2. For the next area you will have to find your own strategy because one slight action makes a big difference to where things are. In the next area, look out on the right for a crawlspace, it will have 20 tranq. bullets. Go to the other end and keep moving right, make sure you stay on the floor until you get to where there is a PMC up above on your right. Crouch and tranq., you can run from now on.

Power Station part 1
Go straight to the right and climb up, climb the boxes then roll over the gap. Ahead there should be a PMC, tranq. him, now look to your left, tranq. him aswell. Get to where the first PMC was and move north. using the solid eye, find out where nearby PMC's are and tranq. them, make sure you always stay low, keep that camo index high! When you reach the mortar emplacement, go to the right of it and roll/crawl down the hill. Use cover to make your way round the back of the power station.

Power Station part 2
After the Drebin cutscene you can choose between two routes, the right one is the easiest but the left has tranq. ammo, if you go right, make sure you have NV turned on so you can see the PMC's hidden above, if you go left, make sure you are always watching the solid eye, there are enemies all over. If you look at your map, you will notice there are 2 ways in the end from the power station. Personally, I think it's best to go left.

Confinement Facility
Take a look at your map at the top there are 2 ways, you want to get to the left one. There were two ways into this area, whichever way you got into this area, use the water and tranq. the guards to make your way to the left path. When you get there, tranq. any nearby PMC's. Turn left and crawl while sticking to the cliff wall, keep going until you get to a path that goes up. (btw at this point my stress was %80.00 but you just have to put up with it. Don't take chances and make sure you get the headshot) At the end of this 'path' there will be ground at varying heights make sure you kill anyone within range before you drop down. Proceed forward and try to take out the PMC in the tower, stick to the right of the area, roll over the barrier, turn right and exit the area.

Vista Mansion
You should, now be on a path, higher than the PMC's who should be on your right, below you.Slowly make your way across the path, knocking out anyone who notices you before you get an alert. When you get the cutscene with the bulldozer, just wait for it to knock down the doors. Enter the mansion grounds and take the stairs on the left, half way up, crouch and continue until you reach the far hedge, shaped like a right angle. Look around it and there should be another one the same. Look to the right of that and you will see a door to the mansion. Crawl there (once your camo adapts your camo index will be at 99% anywhere if you use facecamo in this area) Once you are in, head straight through the door ahead of you, lie down so that the two PMC's coming down the stairs won’t see you. Once they are both gone, go up the stairs and continue until you are outside, there is tranq. ammo for the Mosin Nagant if you want. Drop down the hole and have NV turned on, make sure you don't miss the Mk.2 tranq. ammo. When you are ready, climb the ladder and be ready for Laughing Octopus.

FROG Ambush
Find the machine with lots of wires coming from it and lie down behind it. Get out Metal Gear Mk.2 and stun all the FROG's. All I can say is just be patient and don't be seen. The FROG's come in 4 waves. The fist wave has 4, the second wave has 2, the third wave has 2 and the fourth wave also has 2. If they are grouped and want to separate them, bump into one and they will pause for a while whilst the others move on, then go behind them and stun them.

Another strategy that works well is to hide under any desk or bed and tranquilize them. Even if you shoot their legs they'll go down eventually and their partners will not wake them. The plus with this strategy is you save battery life for the main boss fight. If you have any clips you can toss them into an opposite corner of the room to lure them over. Just be sure the target isn't hitting the underside of whatever you're hiding behind or they'll likely spot you.

Laughing Octopus
You are now free to use lethal weapons!!!! Make sure the M82A2 is in your inventory as well as the FAL Carbine, ad the SAIGA12 (rapid fire shotgun). When she is blended in or on the floor recovering, use an assault rifle or machine gun, when she is walking about, use the M82A2, at close range don't use it's scope and get headshots, 6 of them will kill her. When she blinds you with the ink run away shoot at where you think she is with A.R. or M.G. Use NV to find her when she's camouflaged. Shoot her as soon as she stops firing. Use the boxes (they also have tranq. ammo on)in the southeast room to roll over the top and get away when she attacks you as a ball (this can kill you in 2 hits!!!), she cannot get you in this room on the boxes so it is useful for health recovery, once she actually enters the room you might wan to leave. When her health is half way down, it's best to stick to the M82A2 and just shoot like mad, buy ammo from Drebin if you need. The fight isn't really that difficult. Also watch out for the little bombs she sends at you, they can go through walls too.

Laughing Beauty
You can use the stun knife to conserve your non-lethal ammo, if you can be patient enough you could also use the Mosin Nagant since we won't be using this often.The fastest way to do this is to use a stun round from the grenade launcher but this can backfire if you miss. Remember, DO NOT kill the beauties!! If you kill LO non-lethally you will find the second of 5 dolls required for the Solar Gun on one of the beds but only during the fight against LB (this can be done on any difficulty and you don't need to collect them in one playthrough).

Mountain Trail
When you get to where the paths split, take the left path, continue until you reach the concrete bridge, at the end of it, move towards the rock, don't be heard by the PMC at the other side, he will be facing away so use your stun knife on him. Take the right path this time at the end stop and turn on NV. You will see a sniper PMC, tranq. him and take the path to the right of him, walk slowly because there is a guard at the end of this path, tranq. him and take the left path through the crop circle for a flashback.

Mountain Trail Riverside
It says that the Solid Eye is giving you away when you enter this area when in fact it's just NV so you can keep your Solid Eye on if you want to help keep track of where the FROG's are. Take the left route and always stay on the floor, there should be a FROG straight on the left then once you reach a curve in the path there will be three more. If you move carefully enough then you will only need to tranq. two of them. Proceed straight ahead into the rocky area. On your right there will be a PMC, tranq. him. (I don't know if it is possible for him to set off his own claymore when he falls, it' s never happened to me) For this next part there are many ways and I will leave you to it, it's easy enough to not be seen.

Before exiting this area you should buy at least one of every type of non-lethal ammo. The reason being that during the next section you'll have unlimited ammo but Drebin's shop will be disabled. I recommend stun and smoke grenades, their emotion variants and V-Ring shotgun shells, preferably for the SAIGA 12 since it holds more rounds than the M870.

Vista Mansion
Don't destroy the powersuits as this will count as a kill, ignore Otacon's advice to use the machine gun during this segment. Equip the Metal camo (free download) to reduce damage by half and lie down to recover any lost health as well as avoid being shot by the powersuits. When the PMC's start to climb aboard use CQC or the SAIGA 12 with V-Ring rounds. You have unlimited ammo for this segment so go nuts with stun and smoke grenades. Shooting the powersuits with V-Ring rounds seems to speed things up too.

Confinement Facility
Kill the GEKKO's A.S.A.P. However do not forget about the PMC's, it is vital that you stop them, use CQC like before.

Power Station
Don't destroy the tank, just focus on shooting the doors with the machine gun and using CQC on the PMC's.

High Woodlands Highway
Just shoot the GEKKO's so they can't shoot you.

Marketplace
Get out your rail gun. Go straight left to where the little archways are, all the way to the end. Stick to this wall, go past the GEKKO on it's left until you hit a dead end. Roll over the railing and run to the left of the other railing across the street and down the alley. Don't stop, at the junction there is a GEKKO on the left so stick to the right side but continue forward. Once you pass it, at the corner, start charging your Rail Gun, follow the path and the same GEKKO will be at another junction on the left, shoot it. Now start to charge it again straight away and start moving forward, at the end of the alleyway a GEKKO will appear, shoot it and then immediately charge it up again. Leave the alley and turn right, there will be a GEKKO at the end of the street, swerve left and right while the gun is charging to try and evade attacks. As soon as it is charged, shoot and run for the helicopter. Note - Now your play time should be around 1 hour 35 minutes, or maybe just a bit more. (I'm at 1 hour 14 minutes)

Midtown S Sector
Note - If you are using NV you will probably see what looks like the Resistance Member (RM) peeking round a corner, don't be fooled, it's a scarab (mini-gekko), it can't harm you so just ignore it. First of all, get on your Octocamo and have your NV on all the time. Now trigger the cutscene with the RM. Once it is over you need to turn around and turn left, then take the next left aswell. Ahead and a bit to the right are some stairs, go halfway and stop. Wait until just after the RM has passed you the go around the side of the stairs to get some tranq. rounds for the Mk.2. Get to the top of the stairs and look over the edge to the right, as soon as you see the RM peeking round the corner turn around and move on. Near the end there will be two PMC's to your right, tranq. them and run straight round the corner climb up the ledge and drop off the other side before another PMC sees you turn right, and then again, stay on the left, come round the left side of the van and tranq. the PMC's. Wait for the RM to go around the corner then follow him into the park. Go up the steps and tranq. the first two PMC's. Then instead of following him to the fountain, when it's on your right, lie on the grass ahead of you and blend in, then move forwards until you can get a shot on the PMC's. Quickly get back so the fountain is on your right and get close enough for him to set off. Don' t follow him yet because he will run back for a pee. After he has 'relieved' himself follow him again, on the way past, put another tranq. bullet in the last two PMC's and get the ammo next to them. Follow the RM up the ramp, when he goes down the stairs, he will stop at the bottom and come back up, don'tundefined be in his way, now it's simple just follow him to the exit.

Midtown Central Sector
When you get to the corner the RM will look at you so watch out. When he sets off don't follow him, stay behind the van because he will come back to look at the picture of Minami Akina. Follow him around the first corner and down the stairs, ahead of the stairs are a bunch of PMC's so don't let them see you. Get straight into the water, remember as soon as you surface your Oxygen Gauge will instantaneously fill, also, when underwater, the spotlight can't see you. You can see the RM's legs underwater, find out where he gets out then you get out not so far behind him (tilt the right stick up to surface) Follow him down the alley, however be careful, at first he will stop and turn around.

Midtown NW Sector
Look round the corner, when the RM has crossed the water and started to set off, you follow him, stay crouched in the water. Once the spotlight has passed you, climb out on the right and blend in to the ground. When the RM has crossed back over, climb the ladder on your side. Try and get out so the ladder is right next to you. Once you are up the ladder, turn left and move forward to the far path at the side of the road. Blend in then move to the left until the RM sets off, turn around and get forward as far and as fast as you can without being seen. Keep going in the same direction as the RM. Soon you will see two PMC's, The RM will try to sneak behind them and he would have gotten away with it if it wasn't for that meddling can. (sorry about that one) You need to tranq. them before the RM gets there, you will need a good aim for this one mistake could mess it up. Once they are out of the way move forward up the steps and quickly get to the end and round the corner. Tranq. these two quickly, otherwise the RM will be caught. Also aim with the iron sights (triangle) so you dont hit the railings. If he is caught it isn't that bad, just wait and he will come back round in front of the last two you shot.

Midtown NE Sector
There are so many guards and that pesky helicopter that you aren't allowed to kill. Don't panic just follow the RM, preferably while crawling, if you do this you won't need to fire a bullet.

Midtown N Sector
Get straight on the floor and blend in. Follow the RM. If you lose track of who is who, the SOLID EYE gives you the information about everyone, the RM is the one whose name is in blue and says 'Resistance'. Also, he doesn't have a gun in hand like the actual PMC's. Anyone you knock out will be woken if a vehicle passes so don't expect them to stay down long. When you reach the right of the van, stay there until the vehicle patrol passes, Then look left around the front of the van and tranq. that PMC, go in the middle of the road on the floor and shoot the one on the left. Now turn the corner, ignoring the other two. crawl as fast as you can because the vehicle patrol is on it's way back. If you take the next left you will have caught up with the RM. Depending on what just happened, he will be either on his own or in a group, if he's in a group tranq. them all (except him). Stay close to him from now on it's just the case of crawl - blend - follow. Make sure when crossing a road that you don't take any chances because if you are in the middle of the road and a vehicle patrol comes, well good luck.

Prepare for the next section: When you get to the end of the road after you've passed the patrol and the RM changes clothes again I recommend switching to the Metal camo. Do this before following him passed the next corner to the left and triggering the Big Mama cut scenes. This way you'll receive half damage on the bike chase (as you can't modify camo during this scene).

The Bike Chase
You will be very lucky sometimes and other times you won't be for example, one FROG could hit you twice, but next time they could completely miss you. Even on an unlucky run however, it is still possible. Use stun grenades, smoke grenades, the Mk.2. and swap the VZ. 83 for the Bizon (for use on the unmanned wings) as it as it has a longer clip. Don't worry, you get infinite ammo. *AA = Auto Aim

Church Courtyard
This first part is chaotic, just throw smoke grenade into groups of FROGs and try to knock them out with a well aimed stun grenade. You can take cover behind Big Mama to try and evade gunshot (she can't die). You can try and use AA on the FROGS but here I think it's best to stick to the grenades.

Riverside West
If you have entered this area on low health you can save, set the PS3 clock forward 5 days and your health will be full. I don't do this though because I don't feel right about cheating, I don't feel proud about it. Again any groups just throw a smoke grenade at or a stun grenade in front of them, when you are coming up to the first road block throw a smoke grenade on front of where you will stop (may require practice) then throw a stun grenade at the enemies. When Big Mama turns around, equip the Mk.2 and when it goes slo-mo, shoot the FROG on the turret, quickly switch to stun grenade and throw it in the middle of everyone, tranq. as many as you can, use AA if you want. Then just hold triangle.

Riverside East
Your health is refilled. If you want to you can kill the flying things for points or just ignore them, they never hit you. Equip a stun grenade and aim for the FROG on the turret to the right and hold triangle. If you do this right, you will remain unharmed. Now have AA ready with the Mk.2, a FROG on a ture will be following you, it is all about luck whether you hit him or not. You should come up to a roadblock now, throw as many smkoe grenades as you can so you aren't hit. Equip the stun grenades, and make sure you know when the slo-mo scene is and throw a stun grenade under the trucks as soon as it starts. This should blind the FROGs who are now about to drop down, quickly equip the Mk.2 with AA and shoot like mad, they should all go down in one hit, don't forget to use Big Mama as cover. When she is about to go down the steps, equip a stun grenade and throw one down, then throw another to the bottom of the next steps, when you reach the bottom throw one more down at the ground. Now either switch back to the Mk.2 with AA and shoot non-stop. Once you are under the bridge you are safe. Be warned, whatever health you leave with is carried into the Boss Fight.

Raging Raven
This in my opinion is the easiest boss fight in the game. Equip the Rail Gun and hide in the middle while crouched, using the stairs as cover. Charge the gun and wait for her to come in, take a shot a watch her health dwindle. When you hear the bomb sound,change floors. Get the tranq. ammo in the corner of the room. If you can't find which one is Raging Raven then look at the solid eye, she is the biggest circle. Just shoot her 2 (maybe even just one) more times with the Rail Gun and she's down. If you like you can also try the M82A2 if you can get a headshot.

Raging Beauty
Once again you can use the stun knife to conserve your non-lethal ammo, and also use the Mosin Nagant. Remember, DO NOT kill the beauties!! If you kill RR non-lethally you will find the third of 5 dolls required for the Solar Gun in one of the corners on the top floor but only during the fight against RB (this can be done on any difficulty and you don't need to collect them in one playthrough). Note = You should be at around 2 hours 20 minutes (I'm at 1 hour 45 minutes)

MGS1 Flashback
This is very easy. Run along the right hand side of the heli-pad, when you reach the end, move round the left of the boxes ahead, run under the camera on the right and go into the crawlspace.

Snowfield
Shoot the GEKKO with a fully charged Rail Gun shot, for some reason it doesn't die in one hit so retreat and use the big rock as cover. When it returns shoot it again to finish it off. Proceed ahead, there are no items here that we need.

Heliport
I tend to pause here annd admire the music while thinking back about how legendary the Metal Gear Saga has been. Brings a tear to my eye. Collect the Chaff Grenade from the middle of the heliport (deja-vu?) Leave the heliport by the left ramp and look in that building for some tranq. ammo, this will also trigger a flashback, your tranq. ammo should be at it's max by now (50). I get confused now because everybody sneaks through crawlspaces to evade the Scarabs. Just throw a Chaff Grenade and run straight through. This saves a lot of time.

Tank Hanger
I get confused now because everybody sneaks through crawlspaces to evade the Scarabs. Just throw a Chaff Grenade and run straight through. Roll under the shutter and stay on the right wall. Get out your Rail Gun and fire a fully charged shot at each GEKKO. Move forward to the Canyon area.

Canyon
Nothing to say just run forward, after all, you have kille the GEKKOs.

1st Floor
Don't remember Otacon's password, there is a secret one that you can use. I'll tell you when we get there. If you don't have one, climb in the back of this truck for an FIM-92A. Head to the bulkhead to trigger the conversation, then go to the elevator and go to the floor, B2.

Floor B2
Go straight ahead and make a left at the end then just follow the route. Use the code 14893. This gives you a 100,000 DP bonus, when you enter it correctly you will hear a monkey sound. Go back, when you make a right and there is a narrow doorway ahead of you, start charging the Rail Gun, when it gets fully charged, go through and aim right, as soon as the GEKKO drops down, shoot it. When you go through the doorway, be careful not to hit the Rail Gun on the doorway because it will cancel it. Go back up in the elevator.

1st floor - revisited
Go to the door with the Metal Gear Mk.3. As soon as you regain control of Snake when you see the GEKKO, start charging the Rail Gun and move to your right, under the walkway, once the GEKKO jumps down, shoot the GEKKO.

Snowfield & Communications Tower
Check the little room on the right for some Mosin Nagant tranq. ammo. Now continue to the Crying Wolf battle.

Crying Wolf
When I got to this part of the guide I was stuck at this part of the game. I thought, I can't leave it here so I came up with these tips and used them myself, it worked. Here they are. Always have NV turned on, that way you can find Crying Wolf easily, she will be bright white like the FROGs but she will be off the ground. All you need is the Mk.2, FIM-92A and the M82A2. Mk.2 for the FROGs, FIM-92A for when she is running at you and the M82A2 for when you have found her. Six headshots from this will kill her. Also, when you shoot he, go to where she was and you can follow her footprints to see where she ran to.

Crying Beauty
Once again you can use the stun knife to conserve your non-lethal ammo, and also use the Mosin Nagant. Remember, DO NOT kill the beauties!! If you kill CW non-lethally you will find the fourth of 5 dolls required for the Solar Gun next to the building that you start near but only during the fight against CB (this can be done on any difficulty and you don't need to collect them in one playthrough). After she is defeated, continue through the door ahead.

Blast Furnace
Take the walkway that leads you to a wall, wall hug and mov to the other side, carry on until the elevator is to you left, below you. Throw down a Chaff Grenade and roll over the railing, activate the elevator and press B5. You leave through the door opposite the one you enter. When the doors open, start charging the Rail Gun and shoot the GEKKO. Now wait for another GEKKO to turn up and do the same to this one. I shot the Scarab on the wall with the M82A2 to make sure it would work.

Casting Facility South
I shot the Scarab on the wall with the M82A2 to make sure it would 'kill' it. Continue and be sure to pick up the tranq. ammo next

Casting Facility North
Have a Chaff Grenade in hand crouch and move forwards until you reach a group of inactive Scarabs. Throw the Chaff Grenade near them, as soon as it goes off, move as far forward as possible and turn right. Climb the conveyer belt, drop off directly ahaed of you, turn left and roll over the barrier.

Underground Base
Once you can see Scarabs, throw a Chaff Grenade and make your way to the door.

Vamp
If you do happen to have the Solar Gun, fire one fully charged shot when he is near you and he will go down in one. Here is if you don't have the Solar Gun, it's time to unleash the M6OE4 it has an ammo capacity of 200! When he is about to swipe, do a roll to dodge him. When he's down make sure you have a weapon that says ' CQC ' and the Syringe equipped. When you knock him down, don't stand right next to him because he will knock you away, but stand very close and then run at him but before you press R1 make sure you are not moving otherwise you will try and throw him to the ground. The grenade launcher can also be very useful here. If he is throwing knives, make sure you don't stop moving!when i did this he came right up to me and

Suicide GEKKOs
Stay crouched when charging, this helps recover health, don't move unless the GEKKOs have managed to reach you. Watch for the one GEKKO that appears behind you, only fire fully charged shots.

Surface Tunnel
This is very hard. Take your time and make sure that you don't pass a GEKKO because if it is shooting you from behind you won't get it and it will do a lot of damage. Stick to the gatling gun but beware. It overheats very quickly.

Port Area
Dash forwards at the start and press triangle when the prompt appears. Now use the buildings as cover and full charge the laser, walk towrds it while firing when it drops, press triangle near him. If he fires rockets, dodge them with X or shoot the Gatling Gun. When he charges at you, dodge to the side and then ram him after he stops blocking othrwise it won't be good for you. This fight is quite hard but not too difficult.

I have just found another unbelievably easy way to do this fight, using this I can easily do it without taking any damage whatsoever. Okay, here we go. The only weapon we will use is the Laser. Hide just around a corner where Liquid will start to approach you from around the corner. Make sure your Laser is charged up (even charge Lv. 1 will be good enough) and he should be pretty close to you. Now shoot him with the Laser at the same time as advancing towards him, as soon as he goes down, press triangle and repeat this method. If the Laser runs out of charge, just stay away, use the buildins as cover and keep trying the laser. As I said, when you get used to this, the fight becomes very easy.

Note - You should be at around 3 hours 20, (I was at 2 hours 13 minutes)

Ship Bow
This part is easy. At first just stick to the left side, don' t stop crawling and tranq. all the FROGs that are in your way. When you get to the GEKKO area, dash bbetween cover and don't be afraid to stand up. Just watch out for the two FROGs that jump down near the end. When you have reached the other end another GEKKO will appear. The door is on your right, and there will be a FROG at either side of the door, very high up. Make sure you take them out. Use the boxes that are close to the door as cover from the GEKKOs. Even if it is only one box high, crouching will still hide you. Take out the GEKKOs with the Rail Gun and open the door. Pick up the tranq. ammo on one side before you go down the lift.

FROG Ambush
Turn left 90 degrees into the little hallway, lie down and start tranquilising them. They come in 3 waves, for the first wave, just use the Mk.2 to tranq. them all, making sure you stay low. The second wave will have FROGs that are where they were in the last wave. But first, get out the Mosin Nagant and tranq. the 2 FROGs above on the balcony, now carry on tranquilising them. The third wave is identical to the first wave. Whatever health you finish with is carrried through to the Screaming Mantis fight.

Screaming Mantis
Hardest of all boss fights. TAKE OUT THE ORANGE DOLL FIRST. It may seem stupid but Meryl on The Boss Extreme is a real bitch, she barely stays down when you tranq. her, the FROGS stay down for ages. Once she is gone, it's easy. When SM throws the blades, lie down and stick to the wall. Use the M4 or AK102 on the dolls without taking time to aim, just shoot like mad. When SM holds up Meryl and a frog in front of her, tranq. them and stay shooting the dolls. Don't forget to keep using the syringe and tranq. any FROG that you can see. If Meryl is close, tranq. her, even if she does get straight back up.

-

If you want to keep Meryl down, just use CQC and use the Syringe on her, this should keep her down for a whole 1 round, once she gets up again just use the syringe again. After that just keep aiming for the orange doll (mantis doll) once the doll drops, pick it up and use it as a weapon against Mantis, this should kill her very very quickly.

Screaming Beauty
You'll be glad to hear that you can use all of the non-lethal ammo that you want, you won't be using any more guns now. Remember, DO NOT kill the beauties!! If you kill SM non-lethally you will find the last doll required for the Solar Gun in the little hallway mentioned two paragraphs up but only during the fight against SB (this can be done on any difficulty and you don't need to collect them in one playthrough).

Scarabs
What is wrong with veryone. To get through here without being hit, all you need is a few Chaff Grenades, you only need two. When you see the first scarabs, throw one. wHene it is about to run out, throw another one. See it's simple, if you use three then you will have no problems at all.

Microwave Tunnel
Just one tip, only press triangle fast enough to make the prompt dissapear, it will need to be pressed more frequently later on. This will stop you literally destroying your arm needlessly. Oh yyou don't have to make it completely, the first time I would need 3-4 more seconds to make it past the microwave but it still worked. This made me think you can't die but you can, if you aren't very close to the end, well I hope someone likes to eat microwaved Snake....

THE FIGHT
So this is the walkthrough for the last fight, not only this, it is THE FIGHT, capitalized, your last fight! by Boss Extreme (me...)'''

The fight has three parts, Liquid Snake fight (easiest), Liquid Ocelot fight (normal) and Ocelot fight (hardest). In case you die, I've got some bad news and some good news... the bad news is that you will lose the Big Boss, the Foxhound and the Fox emblem, and will have to start the fight from the beginning. The good news are that you will at least get the Hound emblem!

In my opinion this is the best Boss fight in the whole game, you will hear some music from the other MGS games, and you will finally have an opportunity to beat Ocelot/Liquid once and for all! Also, you will fight on the highest part of the Outer Haven!

Liquid Snake:
This one is really easy, hold L1 (hold it for the whole Liquid Snake part) and press R1 for a strong punch. Dash (stop holding L1, and press X+moving the left analog to the direction you want to dash)and keep dashing until you know you can punch Liquid, then punch him. When Liquid falls on the ground just stand in front of him, when he stands up again, just (I'm sure you will still press L1)punch him twice or three times in case you punched him too early (just keep pressing R1 while holding L1), Liquid will fall again. Keep punching him (remember: not only R1, but L1+R1)until he falls down, and when he stands up just punch him twice or three times again. Keep doing it until he changes to Liquid Ocelot.

I don't know about you but the strong punches aren't very, well...strong. A 5-hit combo by pressing R1 5 times is about three times more effective. Don't go in there until you have just dodged one of Liquid Snake's dash attacks, after this just keep pressing R1. If he does go down, stay next to his body, as soon as he is up, try it again. When you get to where he doesn't go down, dash backwards, quickly! Just to give you an idea of how good this is, before I tried this and I was using power punches and everything else, I couldn' beat Liquid Snake. On my first go of this, I got all the way through to Liquid Ocelot...          ...with no damage until that point!

TIP: If he manages to attack you, he will taunt you, when he doest taunting you, press Triangle to taunt him back and also refilling your health (not the whole gauge, but more than Liquid Snake/ Liquid Ocelot/ Ocelot)!

Liquid Ocelot:
This is less easy, but if you doing everything right you won't lose. Liquid Ocelot will have a new power, a very strong punch that makes you lose a lot of health, beware. When you hear him shouting "take this!" just dash backwards or to any side, when he punches you will be able to either dash attack him (press X and dash towards him and then press R1, CQC him, or just punch him. the CQC and the dash attack are very usefull. Keep dashing and keeping a distance between you and him will result with him doing his special attack, than attack him. After he loses enough health he will become Ocelot, good luck with him...

In my opinion, this is the easiest, just stay away enough that his normal punches can't reach. Now dash sidewards in one direction, he will do a powerful punch while saying 'Take this!'. Because you are dashing he will miss, as soon as he misses, get close and press R1 lots for the 5 hit combo. Get away and repeat, Use this easy section to refill your health if you need, let him taunt you then you taunt back.

Remember: when he taunts you press triangle to refill some of your health.

Ocelot:
The hardest of the three and last boss in this very long game you probably finished in 5 hours if you did everything right. He is the CQC master, so beware! Don't get too close to him, he will headbutt you, and believe me, it hurts!. In case he uses CQC on you, wait for the moment the 'Push the ******* triangle' button appears, then you will be able to do a counter attack. Well, another attack (I guess you will like it) of him is the sleeper hold, guess what it does? yes! It makes you sleep! not a good thing. Don't let him hit you, when he hits, dash backwards and try to dash attack him. Don't try to attack him when he stands up after you punched him and he fell to the floor, he will be too fast for you to attack him. No special tips for that one, just hit him, and dash, dash a lot.

I agree, just repeat the dash attack, if he doesn't flinch at all, dash backwards, if he flinches, dash attack again, if he falls to the floor, step backwards.

After you beat him (be happy!)both of you will fall on the ground, this last part is just beautiful! First, go near him, 3 steps, and press R1, you will see Snake punching Ocelot, than just keep pressing R1 until you will see Ocelot himself (!!!!!!!) being beaten by you. BEWARE! He can kill you too if you miss a punch, just make sure that after the slow-mo cut scene you move forward again to punch him.

Watch Ocelot die, it will be funny.
