Gears of War: Judgment has a slew of retailer-specific pre-order bonuses for players around the world, covering the US, UK, Canada, Australia and the Netherlands. In the US, those who order from the Microsoft Store get the Classic Hammerburst weapon and Gears of War comic heroine Alex Brand as a playable character. In the UK, order from Shop To and get the same goodies.
Order from EB Games in Canada to grab the Hammerburst, Alex Brand skin and the "Young Marcus" skin, which allows players to be Marcus Fenix as he appeared six weeks after the end of the Pendulum Wars. Australians can pre-order the Special Edition from EB Games to get the game, a steelbook case and the Alex Brand and Anya Stroud skin unlocks. Players in the Netherlands who order from Game Mania get the Hammerburst, Alex Brand and Young Marcus skins.
As noted previously, pre-orders from Amazon get the Hammerburst and the "Young Dom" multiplayer skin.
