RAAM’s Shadow debuts today for Gears of War 3 on Xbox Live Marketplace. Available today on Xbox LIVE for 1,200 Microsoft Points, the second major game add-on for Gears of War 3 promises more than three hours of new campaign gameplay and missions on both sides of the Locust war.

Set in the chaos of post-Emergence Day Sera, RAAM’s Shadow drops players into a new team of Gears known as Zeta Squad as they attempt to evacuate Ilima City and protect the citizens against a Locust Kryll storm. Taking on the Locust leader from the original Gears of War, General RAAM, Zeta features the familiar faces of Michael Barrick (from Gears of War comics fame), Lt. Minh Young Kim (Gears of War) and Tai Kaliso (Gears of War 2), and introduces a new female comrade, Alicia Valera.

In addition to fighting as a new squad of Gears, players will step into the boots of RAAM himself, and for the first time storm a human stronghold from the perspective of one of the series’ most legendary bosses. On top of the new campaign experience, RAAM’s Shadow features the Chocolate Weapon Set, new Achievements worth an additional 250 Gamerscore and six new multiplayer characters, including General RAAM, the Theron Elite Commando, Alicia Valera, Lt. Minh Young Kim, Tai Kaliso and Michael Barrick.
