Summary: The game has a bit of a learning curve, as does each map. After you overcome that along with learning how your class of choice fits into your teams struggle vs. waves of mutant scum, it becomes a blast.
Summary: Reading a lot of reviews written by people who didn't like the game, I can honestly say that they played it completely wrong. It seems like they are missing a key element that makes this game fun and more than worth whatever they payed: friends. This is a coop game in every sense of the word.
Summary: This game is alot of fun, I love the 'skill tree' aspect, the wide array of guns, and the maps. the HUD is nicely done and no cross hairs make the game even more realistic. over all this game is great..... for single player.
Summary: Considering the price and the fun you get, plus quite good graphics, when you push them to the Limit - I say you will not regret the purchase. Bought it the 3rd time now (for one friend after the other :-)
Summary: This Game is immensely fun and a great buy! The Multiplayer is sublime, but the solo games aren't as hoped. They are still good but its definitely not as exciting as those found in Multiplayer.
