Announced at the Nintendo Direct live stream earlier today, a crossover game for the Nintendo 3DS between Capcom, Sega and Bandai Namco is in development. The last of these three is also doing the publishing and one of their developers, Banpresto, best known for the Super Robot Wars franchise, is making the title.
That’s all that there’s known at the moment. Any details like what franchises appear in the game or if the game will even hit stores outside Japan still need to be announced. You can visit the teaser site here, but there’s not much there to discover besides the company logos. Still, whatever this is may be worth keeping an eye on.
