#7 Gears of War 3
Gears of War 3 is the final chapter in the Gears of War trilogy, but it isn’t the end of the setting, which is set to be expanded in a prequel trilogy (much like Star Wars) that begins with Gears of War: Judgment. While the latter game is still a few months off, Gears of War 3 has been out for awhile, and represents one of the best cooperative experiences on the Xbox 360—the platform to which it’s exclusive.
The game allows players to once again jump into the roles of Marcus Fenix and his brother-in-arms, Dominic, as they stand as the last line of defense against the evil dudes who call themselves the Locust, and the queen who leads them.
