Pre-orders for Gears of War Judgment went live last week. Every pre-order for GoW Judgement comes a Classic Hammerburst, no matter where you pre-order it. It’s not just the skin, but the actual in-game weapon. Different retailers are offering different character skins for pre-ordering through them though.
The skins that are being used to leverage pre-orders are Young Marcus, Young Dom, Anya and Alex Brand. Young Dom can be obtained through a pre-order with Amazon. Pre-order with Gamestop stop and receive Young Marcus. Still searching for where the other two skins can be obtained, if you find out before I do, let me know.
