The game does a lot right, and a few things wrong.
The wrong is the short story (should be longer since it's the final game), the fact that it feels and plays exactly like the first two, and that the game really doesn't innovate at all for the series in general, I could have been playing a Gears of War 2 expansion pack and I wouldn't have noticed the difference.
