 As the game progresses the overall feel becomes increasingly dark; from the initial briefing which consists of confronting images of dying animals, famine and industrial pollution, through the increasingly paranoid rantings of Private Michaels to the distressed and teary messages from Griffins mother and girlfriend.The gameplay itself is extremely linear in nature, as is normally exhibited by interactive movies and the player's input is limited to conversing with other characters (through a choice of pre-existing phrases) and some involvement during missions.The game is unusual in that the player 'wins' only by having their character die (or possibly fall unconscious as this, like so much else in the game, is never made completely clear).
