Gears of War: Judgment's OverRun mode lets two five-player teams alternate between playing as COG soldiers and Locusts, and the objective-based mode is being included as a GameStop pre-order incentive.

Those who pre-order the game as a PowerUp Rewards member will get four-days early access to the mode starting on March 15 in advance of the Xbox 360 game's March 19 debut. If you've already pre-ordered it, don't worry, as you're covered retroactively.

Also, any multiplayer XP you get in the mode will carry over once the game comes out for the first week following its release.
