Damn fun game. Pity I needed the Hard Drive space and my internet isn't the best, but it was well worth it just for the fun to go around killing zombies. Not to mention it's fun when you get to play as the zombies.

Edit: Had quite a bit of fun with this game whilst playing it. The way the AI director adjusts things is so interesting as the items are not in the same location and then the special infected like Witches and that are often placed in new and different locations where no two sessions are the same.
