Description:
From Valve (the creators of Counter-Strike, Half-Life and more) comes Left 4 Dead, a co-op action horror game for the PC and Xbox 360 that casts up to four players in an epic struggle for survival against swarming zombie hordes and terrifying mutant monsters.
The Sacrifice is the prequel to The Passing, and takes place from the Left 4 Dead survivors’ perspective as they make their way south. You may read the comic to find out the official version of events, or you may play the game to choose your own ending.
