Namco X Capcom is a turn based RPG that features 200+ characters from both companies like Ryu, Jin, Arthur, and KOS-MOS. I don’t know about the system, but the game was originally meant to be a Namco all stars RPG to celebrate the company’s 50th anniversary. The game will also have an anime intro made by Production IG.

IGN has more details

Sounds like serious fun to me. And how can you resist a game with our beloved Capcom characters in an RPG setting from the creators of Xenosaga? And with anime sequences by Production IG (same people who did the Kill Bill anime sequence)! It’s set for Japanese release in May 6. I hope North America isn’t being an ass and looking this game over.

Thanks, Delurio, for the heads-up. Screenshots found here.
