An interactive trailer for Dead Rising 3 has popped up on the Xbox YouTube channel today. Challenging viewers to find a path to "the after party," the trailer constitutes a whole mess of short (~30 second) clips followed by a choice between two further clips, with each demonstrating another way to deal with the zombies plaguing Los Perdidos.
It'll probably take you a good bit of time to see all the footage. My run from start to end involved seventeen videos, and I know there are quite a few I never chose. It certainly does a lot to make Dead Rising 3 look expansive. And gory.
