Kokuga (コクガ) is a shoot 'em up game released by G.rev in 2012 for the Nintendo 3DS. It was directed by Hiroshi Iuchi, famous for his seminal shmups Radiant Silvergun and Ikaruga. Unlike many world-wide releases, the game wasn't released in Canada and the developer was only notified that they would not be able to, late in the preparation process.
