Gears of War 1&2

Gears of War takes place on the planet Sera. A radioactive liquid called Imulsion became a highly valued power source after a scientist discovered how to use it, and the economic shockwave led to several wars between nations. The Coalition of Ordered Governments (COG) originally existed only as an obscure world-government philosophy, but it evolved into a legitimate, though minor, political party during the 79-year long Pendulum Wars. After "Emergence Day," when the Locust began their attack on humanity, the COG were the ones who took the necessary steps to ensure the survival of human civilization, instituting martial law and taking charge of the effort against the Locust. Fourteen years later, the COG is the only human government left on Sera.[7]
The game focuses primarily on Marcus Fenix, the main character, and Delta Squad (consisting of Marcus Fenix, Dominic "Dom" Santiago), and some side characters such as Colonel Hoffman, Anthony Carmine and Lieutenant Kim. Players take control of Marcus Fenix, freshly rescued by Dominic Santiago from the Jacinto Maximum Security Penitentiary. When in co-op two player, the second player assumes control of Santiago. All four of the squad members are available for play during multiplayer games, along with Private Anthony Carmine, Lieutenant Minh Young Kim, and Colonel Victor Hoffman, in addition to the various Locust characters.
Some of the characters received voice-overs from popular culture icons. Marcus Fenix is voiced by John DiMaggio, General RAAM and many Locust creatures are voiced by Dee Bradley Baker and Augustus "Cole Train" Cole is voiced by Lester "The Mighty Rasta" Speight.
