Super Spy Hunter, known in Japan as Battle Formula(バトルフォーミュラ?), is a vehicular combatvideo game developed and published by Sunsoft for the Nintendo Entertainment System. It was originally released in Japan on September 27, 1991, and later released in North America as an unofficial sequel to Spy Hunter. Sunsoft America released it as a sequel due to releasing the NES version of the original Spy Hunter with permission from Bally Midway. The Japanese version Battle Formula was rereleased in Japan for the two-in-one Sony PlayStation game, Memorial Series SunSoft Vol.6, which also included Gimmick!, another SunSoft game which is also known in Europe as Mr. Gimmick.
