The first piece of story-related downloadable content for Gears of War 3 actually precedes the entire series. RAAM's Shadow explores the story of the first game's villain, and will take you about three hours to complete.
In addition to the campaign expansion, a total of six new multiplayer characters will be included as well as the Chocolate Weapon Skin Set.
The pack is set to launch on December 13th and will set you back 1200 MSP. In the meantime, you can take a sneak peak at what to expect via the videos below.
