First post guys so please don't shoot me down!
But I have found Left 4 Dead 2 on the PC for a crackin' £18.99! Great for a stocking filler or any zombie loving fan!
The sequel to the critically acclaimed Left 4 Dead, Left 4 Dead 2 for PC takes play in the deep South of the USA. Set in a modern day survival-horror universe, the co-operative gameplay of L4D casts four "Survivors" in an epic struggle against hordes of swarming zombies and terrifying "Boss Infected" mutants. Left 4 Dead 2 on PC adds melee combat to enable deeper co-operative gameplay, with items such as a chainsaw, frying pan, axe, baseball bat, and more.
Introducing the AI Director 2.0, L4D's dynamic gameplay is taken to the next level by giving the Director the ability to procedurally change weather effects, world objects, and pathways in addition to tailoring the enemy population, effects, and sounds to match the players' performance. The result is a unique game session custom fitted to provide a satisfying and uniquely challenging experience each time the game is played.
Featuring new Survivors, boss zombies, weapons, and items, Left 4 Dead 2 for PC offers a much larger game than the original with more co-operative campaigns, more Versus campaigns, and maps for Survival mode available at launch.
