Gears of War 3's 1st DLC will be a campaign add on and will feature the Graphic Novel's hero Michael Barrick. Those of you who have already paid for the Season Pass will get this DLC for free. The other three DLC is still unknown.
Design Director Cliff Bleszinski said future DLC won't be the graphic novel, but it will have all new campaign content that doesn't have Marcus, Dom, Cole and Baird in it. Expect Barrick and more...
It has been rumoured that 3 multi player maps have leaked as well going by the names of Azura, Blood Drive and Rustlung. Although these maps are not currently available in the game, these could be used in a future multiplayer DLC.
No price, date or name as of yet but will update you soon as we hear more.
