Half-Life: Decay
Featured in the PS2 release of Half-Life, Decay follows a story running parallel to that of Half-Life, Opposing Force and Blue Shift, featuring two of Gordon Freeman's colleagues unseen in other games. Designed for co-op play, the player must switch back and forth between the two characters if playing alone.
