Arcus Odyssey is an action role-playing game video game developed by Wolf Team. The game was released in 1991 for the Sega Mega Drive/Genesis, Sharp X68000 and Super Famicom. It featured an isometric perspective and cooperative gameplay. The game is a cross between fantasy and science-fiction themes,[citation needed] with hack and slash gameplay reminiscent of dungeon crawlers such as Dragon Slayer, The Tower of Druaga and Gauntlet. Arcus Odyssey is part of the Arcus franchise, which also included Arcus in 1988, Arcus II: Silent Symphony in 1989, and Arcus III in 1991. The music for the game was composed by Motoi Sakuraba, who also did the music for the Star Ocean series. An American version for the Super NES was planned, but it was cancelled following Sega's acquisition of Renovation Products (American publisher for Wolf Team and Telenet games). The Super NES version was, however, released in Japan, with the title Arcus Spirits.
