Imagine you and your buddies are in a strike, shooting aliens and stuff, and on your way to the boss, Ghost notices that there's an unoccupied fallen walker lying around. Next thing you know, you guys are demolishing everything in your path! Captains try to stop you with scorch cannons, but fail miserably as you mow them down with the machine gun. Dregs come in on their Pike's only to be decimated by your cannons. Just when you think it couldn't get better, another walker challenges you. Find out what happens next! It would also be cool if these vehicles of destruction could be featured in the crucible too. Maybe in a mayhem combined arms mode?
