Project Cerberus (プロジェクトケルベルス) is a 2010 fighting game for the Sony PlayStation Portable by Milestone and Hobibox. The game was also planned for release on the Sega NAOMI which was shown in teaser trailers, but this version was inexplicably cancelled, and no other version materialized. Incidentally, Milestone released Radirgy Noa on NAOMI two months before Project Cerberus was released.
