Today Epic Games and Microsoft revealed that anyone who pre-orders Gears of War: Judgment will receive some special incentives regardless of which retailer they pick it up from. The content will be multiplayer exclusive and will take the form of the Classic Hammerburst, which was a standard weapon of the Locust Army during E-Day.
As for retailer specific bonuses, they will include special multiplayer character skins for Young Marcus, Young Dom, Anya, and Alex Brand. Currently the retailers which will carry each skin have not been revealed though Microsoft has said that they will do so in the next few weeks. Until then, you can check out the Classic Hammerburst in the video below.
