Following the events of Gears of War 2 where a COG-authorized mission to sink the city of Jacinto using a Lightmass Bomb, Gears of War 3 will give players an opportunity to fight for the survival of the remaining human race. Now, Marcus Fenix and Co. have to square off against the vicious Locust horde and much more powerful Lambent-infected baddies.

The full trailer is much better than the ten second teaser Microsoft offered two weeks ago and gets extra points for its use of "War Pigs" by Black Sabbath.
