A Gears of War: Judgment multiplayer demo is set for release on the game's US sale date, March 19.
The demo will include new multiplayer mode OverRun, an objective-oriented game featuring five-player teams playing as Locusts and COG soldiers, each playing as various character classes.
In North America members of GameStop's PowerUp Rewards program who pre-order the game will gain early access to the demo from March 15.
Multiplayer experience points will carry over to the final game for players who purchase and play judgment in its first week of release.
GameStop US customers will also receive two exclusive pre-order bonuses:
"Young Marcus" character skin - "Decorated war hero Marcus Fenix is the legendary leader of Delta Squad, a small group of COG soldiers responsible for saving mankind from destruction at the hands of Locust and Lambent forces. This exclusive character skin takes Marcus back in time, six weeks after the end of the Pendulum Wars, and during the chaos of Emergence Day - a time before he was hardened by his long imprisonment."
Lambent weapon skin - "This exclusive weapon skin lets you show off your grub-slaying exploits and customize select weapons with the emulsion of your fallen Lambent foes."
In the UK pre-order incentives include GAME's Marcus multiplayer skin, Tesco's Dom multiplayer skin and Shop2's Alex Brand multiplayer skin, while other stores will be offering an Anya multiplayer skin.
Additionally, everyone who preorders Judgment from any retailer "worldwide" will receive the Classic Hammerburst, Microsoft's said.
