Prison cell

One constant element throughout the Metal Gear games is that of a Prison Cell. In almost every game, the player is tortured in some manner or another, never failing to be locked in a cell afterwards. This often leads to an escape challenge.

The first prison cell sequence in the games exists in the original Metal Gear, during which the player must punch through a wall to escape. The concept was expanded in Metal Gear Solid. Following Revolver Ocelot's infamous torture sequence, the player must trick the guard, Johnny Sasaki, into entering the cell (either by playing dead using the Ketchup or by hiding under the bed), and then escape after disarming him. In Metal Gear Solid 3, an almost identical sequence exists (even to the point where the guard is Johnny Sasaki's grandfather). The only major differences are that death must be faked using the fake death pill rather than ketchup, or an alternate solution, whereby the player can call a secret frequency to open the door himself, is implemented.

In Metal Gear Solid 2, a cell aboard Arsenal Gear (almost identical to the cell from MGS1) makes an appearance. Although Raiden is tortured here, there is no real escape challenge because Olga automatically calls Raiden to release Raiden's restraints.

In Metal Gear Solid: Portable Ops, the player has to rescue Naked Snake from a prison cell after he was captured and tortured by Cunningham. NakedSnake also breaks out of a prison cell in the beginning of the game.
