If you haven't heard, there's a giant game festival going on in Leipzig, Germany right now.  Capcom has released what can best be described as a "kick ass" trailer for the upcoming co-op friendly Resident Evil 5.  How kick ass?  Well it's got: explosions, dirt bikes, mini guns, zombies, some big executionor with an axe and a weird dude in a bird mask.  Shall I go on?  Ok, there's exploding heads, slimy worm like creatures, decaptations, and a hot girl in a nurse outfit.  Yeah, I think that about covers it.

On top of the awesomeness that is that official trailer, GameTrailers has some video footage of the co-op play from the game.  After watching all this footage the game has gone from a "Yeah I'll buy that" to a "Must buy."

Watch both trailers after the read more link.
