Here are screenshots for Capcom's Power Stone, an action/fighter currently in development for Sega's Naomi arcade development platform. There's not much info available at this point, and there's no release date yet. But we do know that the game will be released later on the Dreamcast.
The game was first unveiled at Sega's New Challenge Conference II, which took place right before the Tokyo Game Show.
