My favorite in the series
Missing:chris (would have made the game perfect for me)
Added: a boss that chases you for virtualy the entire game, selection screens to choose your own fate in certain predicaments, gun powder to create your own bullets, new gameplay mechanics (blowing up oil canisters, real time stairs no more going down steps and thinking your free from danger)
problems:still feels a bit like 2 gameplay wise, just certain things like still being able to clear a room full of zombies without geting damaged, i mean really how many times can you just see a zombie and walk past it, but the game does a good job of adding many enemis into one area, almost ten at one time in the game
