Microsoft just showed off a bunch of trailers. Some for all-new games! Like Crackdown 2 and Left 4 Dead 2.

Crackdown 2 seems to take a different approach than the first, with the city infected with some kind of plague that's turning people into zombies/monsters. You, naturally, have to kill them.

Left 4 Dead 2 features an all-new cast, will include a range of melee weapons (like frying pans and chainsaws!) and will be out on November 17.

More details to come later in the week.
