It's 1am Pacific, the night before E3 press conferences begin. Time to announce a game ... ? Atlus and Ace Team live to surprise us, and have done so with the late-night reveal of Zeno Clash II.

The first-person fighter followup features a new, open world, brimming with "most of the characters, enemies, and items from the first game--all of which return with dramatic visual enhancement" as well as a host of new characters and items. RPG elements are in, and the fighting system has been updated to allow more precise strikes. And, even more dramatically, drop-in, drop-out co-op is in.

Basically, this sounds unexpectedly enormous, and we're surprised to see an early 2013 release window attached to the ambitious project, for PC, XBLA, and PSN (for PS3). They must be working non-stop .
