Demon's has been out for some time on PC, but has only just launched on console and this means we get an all new trailer than shows off some of the up to four player local co-op that the game has:

The central conceit of the game is that you (and up to three of your local co-op buddies) take control over one of four Urican, astral demons that are used to being the "top of the food pyramid." After three mysterious entities arrive and change the world, the demons must fight for survival and recover their precious food source: the crystals. So you'll take 'em all down by utilizing some impressive weaponry, like missile launchers, and whatever power-ups you can nab, like speed boosts and something called "Bullet Time."
