Gears of War 2

Months have passed since the initial conflict with the subterranean Locust, but peace proves fleeting on Sera when the enemy emerges with devastating new tactics—systematically dragging entire cities into the earth. Facing annihilation at humanity's final bastion, the Coalition of Ordered Governments commits its forces to a desperate counteroffensive, driving deep beneath the surface to confront the Locust threat at its source. Sergeant Marcus Fenix and Delta Squad venture into these hostile underground territories to mount a direct assault on the enemy's stronghold, even as Marcus's friend Dom Santiago pursues a parallel mission born of personal tragedy, searching through the darkness for his vanished wife.
