Atlus and Ace Team have just announced Zeno Clash II. A first person fighter game with a lot of enemies, characters and items from the first game.

Zeno Clash II will be released in 2013 for Pc, Xbox Live Arcade and Playstation Network (PS3).

According to Joystiq:

"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."
