I gave this game an A for two reasons. One is that this game kicks the ass of a lot of other games. And because after you play it for 10 days straight, it gets old. Then you wait 3 days and it's good. The game has a lot. Shooting, mutants, an AWSOME sub acuatic world, robots, big daddies, powers, and exilerating story, a lot of things to do once you get farther, the list goes on and on. My reviews arn't much, but, this game is definitly a buy.
