Graphically good (but not great), outdated motor (animations sometimes weird characters and numerous collisions). A game that was technically excellent it a few years ago, but not in 2011. In contrast: the environments are vast. good price / quality ratio since the game is very long if we do all the side missions, though it seems to be the courier of all survivors ... a bit repetitive! it freaked at times before tough and fast zombies, so good atmosphere for the fans of the genre. and above all playable in coop to 4!
