Metal Gear Acid

Metal Gear Acid is the first Metal Gear to be released on the PlayStation Portable.

While the Metal Gear series, despite being stealth-based, has always had a heavy influence of action, Metal Gear Acid is not action-oriented, but focuses on turn-based strategy (this is possibly why the game's logo lacks the "Tactical Espionage Action" tagline featured on all of the Metal Gear Solid games). It uses a trading card-based system to control the main character's movements and actions.

Metal Gear Acid is a "side-story" and not part of the series' main storyline (similar to the earlier Metal Gear: Ghost Babel, and the even earlier Snake's Revenge). While the game features an all-new cast, card sets are availble which features characters, weapons and items from each of the previously-released Metal Gear Solid titles, as well as a "Chronicle" set which covers Snatcher, Policenauts, Boktai, Zone of the Enders, Metal Gear: Ghost Babel and Metal Gear 1 and 2 are depicted on the cards used by the player.

Story
A plane has been hijacked by an unknown terrorist threat and it's up to Solid Snake to infiltrate the enemy and put an end to this dangerous crisis.

The story starts out with Teliko moving from building to building running away from the guards. The view then changes to the inside of an aeroplane where to dolls, Elsie and Frances, are holding several people hostage. The game then cuts to Solid Snake as he infiltrates an Lobito Island in search of the secret project codenamed "Pythagaros". To help Snake in his mission, he gains the help of Alice Hazel, a psycic. Snake finds this as a joke and doesn't take Alice seriously. He meets a lone man in the control room called Gary Murray. Gary helps Snake to find Dr. Flemming by telling him his location. Snake then goes to the Residental Block to find Dr. Flemming. Once in the eastern building Snake must register so that he can enter rooms to search for Flemming. However he was already registered a Hans Davis, which suprises Snake. When he finds Flemming he finds out it was a decoy and meets Leuitenant Leone. Murray had led him into a trap. It looks bad for Snake but then Teliko shows up and helps Snake.
