IGN is reporting that Genki will release a sequel to mech sim Carnage Heart, entitled Carnage Heart Portable, this summer in Japan. Carnage Heart was a niche success on the original PlayStation, thanks to somewhat unique gameplay involving building and programming mechs before sending them into battle. The PSP sequel promises more of the same in portable form.

A release outside of Japan has not been announced at this time.
