I thought it was a great game. Just don't start playing it expecting Quake, or you'll probably hate it. The controls take a bit to get used to, but they're pretty intuitive once you get used to them. The game has tons of strategy, and it has skeletal animation, which means you can blast a guy with a shotgun, and he'll fly across the room, or cap a guy in the back when he's eating, and he'll slump onto the table. The demo sucked, it didn't give you a good feel of the game. You should try out the full game, just get it at Electronics Boutique, or somewhere else that has a good return policy, in case its not your thing.
