After sinking a lot of free time over the course of a month I can wholeheartedly recommend this game to anyone that is a L4D fan or just a fan of either Zombie or 4p co-op games. Overall the game is well polished, the mechanics are sound. The upgrade ability of your characters, their weapons so you can replay each level with increasing difficulty is just awesome. The devs continue to update the game, patch small bugs and soon new levels and features.
