Codename (gameplay)

In the Metal Gear series, starting with Metal Gear Solid, after the player completes a playthrough and/or meets certain requirements, the player usually earns a codename.

Metal Gear Solid 2: Sons of Liberty
NOTE! When playing Tanker-Plant, there is three scripted Alert- modes.

Mech destruction= Destroyed cameras (both gun gameras and surveillance cameras), UAVs and Metal Gears. In both Extreme modes, you have to destroy 20 RAYs to complete that boss fight, so you are allowed to destroy 39 cameras and UAVs.

Ammo used= Game counts every shot you make with gun that fires bullets (lethal or non-lethal) and missiles. Weapons that don't count are: Cooling Spray, Magazine, any kind of grenade, empty magazine and H.F. Blade.

Clear Caution Modes= This means caution mode what started after Alert.

All stats can be seen in GAME OVER- screen.

Metal Gear Solid: Peace Walker
Because of various gameplay changes in Peace Walker, Codenames, unlike previous games, do not require the completion of a playthrough to gain it. Instead, it only requires beating various missions a number of times. Likewise, the requirements for gameplay have been reduced to the types of weapons used to defeat enemies, the player mode it was done in, and whether the use was lethal or non-lethal for the most part. In addition, Insignias are issued for the various tasks involving the (lack of) use of recovery items, (not) triggering an alert, among others.
