Done well and good Multiplayer. Though its very poor for single player.
But when you look at the single player game its very short. Done on heroic it only took 2 nights to beat. There is some replay with the skulls you can find but honestly I didn't care since i really was bored just playing through the single player, very repetitive fights, and the scripted moments didn't give me any sense of awe. I didn't care what was going on at all. So ya the single player for me was a write off and basically a waste of time.
As for multi-player I had quite a bit of fun with it. I really liked how in open games you had to push your dpad to talk. This filtered out everyone unless they had something important to say. I have yet to encounter a kid screaming during a game, though i do hear it in the lobby but the game made it very simple to mute people without having to go into your xbox menu, these are two of the best features yet on a live game, and they are so simple. The replay is incredible and its fun as hell to watch clips over and over. There is no rewind but thats getting picky. The gameplay itself in multiplayer is solid. One of if the smoothest multiplayer game I have played and they must be commended on that.
I am probably done with the game itself though i may still pick it up from time to time. But still if you are a big into multiplayer there is no reason for you to not pick this up. If you just want a single player game skip it.
