THQ just released a new trailer of Warhammer 40,000: Space Marine, showcasing the new co-op Exterminatus mode, that will be released on all platform on October the 25 as a free DLC.

The new mode includes all the customization options and weapons of the previous competitive multiplayer modes, and introduces optional challenges and mandatory objectives to spice up the gameplay.

Judging at how fast the experience points accumulate in the video, it will provide a large experience boost to those that lagged a bit behind the leveling curve.

You can see the video past the cut, while we wait to be let loose on some (almost) helpless Orks.
