Along with an unlockable port of DoDonPachi, Cave's recently released Xbox 360 title Instant Brain features another unexpected bonus designed to appeal to fans of the company's work.

Andriasang reveals that Instant Brain also includes Nin2-Brain, a Kinect-compatible version of its Xbox Live Arcade platformer Nin2-Jump. It's unknown if Nin2-Brain features new content or if the update only adds Kinect support, but it's a welcome addition all the same -- I really enjoyed the XBLA version, personally.

Man, at this point, Instant Brain seems less interesting as a visual novel and more appealing as a Cave compilation. Why not throw in a few more arcade ports while you're at it, Cave? Just rewrite the game's story so that the characters have to win a Uo Poko tournament, or something.
