Can be pretty fun...
The graphics are a little too shiny at times and, as i like to say, blind you to the point of tears. The charecter models look a little too cartoony for a next gen game. Meanning that they have little to no face animation. And the animations that they do have, look forced. As in unatural.
The sound is very different. The guns dont pack that o-so special that you expect from a FPS. But other than that, the sound is pretty good.
The multiplayer is a little dissapointing though. There are only a few maps. While you can make them bigger or smaller if your the host, they al feel the same. And they are a little confusing at times. They are very weird. As in, you can get lost in a single room. And the action is very slow paced.
So if you own a 360, be weary about this game, while it's all together a good game, it's not for everybody. I suggest a rent first.
