Gears of War (Xbox 360 used game)

A Nightmare from Below. A Hero from Within.
The planet lies in ruin - cities crumbling, Mans greatest works fallen. Humanity is cornered, nowhere to run. The Locust Horde has risen, and they will not coming. They will not stop killing.

The Coalition is desperate for soldiers. The sick, wounded, the imprisoned are all that remain. An inmate named Marcus Fenix, once left to die, is now charged with keeping humanity alive. He can take comfort in but one fact: The human race is not extinct. Yet.

•Take cover and return fire! with the intuitive one-button cover system to blind fire, evade, flank, and ultimately destroy the nightmarish Locust Horde.
•Lead your ragtag squad as Mercus Fenix, or recruit a friend to play squadmate Dominic Santiage and complete the full cinematic campaign cooperatively-online or off.
•Dominate online in Human vs. Locust squad-based multiplayer. Eliminate downed enemies with a kick to the head or a taste of your chainsaw bayonet.
