Overall this is another fantastic title from Epic and it definitely lived up to the hype. The A.I. in this title is also very impressive. The Locust will lull you into a false sense of security and then pounce on you when you are least expecting it. If you are trying to line up a shot with your sniper rifle, chances are they won't stick their heads out so you can shoot them. Your ally A.I. is smarter too. The storyline is much more immersive and fulfilling.
It is a great feeling whether you are going through the campaign with a friend or taking on waves of enemies with a group of your buddies. The environments are really varied so there shouldn't be much of a "déjà vu" sentiment among gamers. You also get to drive more vehicles in this game which help to change up the pacing. Gears of War 2 is a hell of a ride and one everyone must experience.
