Beat Gears of War 3 on Insane, unlock Mission Impossible weapons

Your mission, if you choose to accept it, is to beat the Gears of War 3 campaign on Insane difficulty by December 25th. If you succeed, you'll be awarded the "exclusive Mission: Impossible - Ghost Protocoal Weapon Skin Pack," which includes five extra weapons skins: a "Ghost Protocol" Lancer, Hammerburst, Retro Lancer, Gnasher Shotgun, and Sawed-off Shotgun.

If it wasn't obvious, this free DLC giveaway is part of a promo for the new Mission: Impossible movie.

Starting tomorrow, Xbox Live will feature the "Ghost Protocaol experience," which includes a giveaway. You can win a custom slim Xbox 360, Kinect, 50" HDTV, 5.1 home theater system, and the Mission: Impossible series on DVD. To enter, just watch the trailer on the Xbox 360 dashboard.

The Gears 3 bonuses will be reserved only for gamers that can beat the Insane campaign, in either single or multiplayer. If you've already completed the campaign on Insane, you'll automatically receive the weapon skin pack by the end of the year.
