Gears of War 3: Raam's Shadow (360) vs Monday Night Combat (360)

RAAM’s Shadow adds more than three hours of campaign gameplay, featuring missions on both sides of the Locust War. As the COG, play as the veterans of Zeta Squad: Tai, Minh, Valera, and Barrick. As the Locust, you are the fearsome General RAAM with all new executions and the power of the Kryllstorm. Also included are 250 Gamerscore, the Chocolate weapon skin pack, and six new character skins for Versus multiplayer.

Monday Night Combat is a class-based, third-person shooter … and the most popular lethal sport of the future! It blends intense combat, finishing moves, and gameshow-like challenges and rewards to produce an action experience unlike any other. Why fight for "honor" or "duty" when you can fight for the real American dream—cash, fame and endorsements?
