Great game! Anyone who is giving this a down vote must be extremely butt hurt. The beta was bad but between then and lauch they fixed a lot of the issues the game had. The perk cards and randomized enemy card system bring loads more replayability to this than L4D. Now only that but the characters are a blast. They are also distinct and have pros and cons to them which can change how a group plays the game. You can essentially craft classes with cards that can make you an unstoppable melee beast or full time medic. It's amazing how much this game breaths new life into the L4D archetype of games.
