Cosmic Spacehead review. Classic Game Room presents a CGR Undertow review of Cosmic Spacehead for the SEGA Genesis developed and published by Codemasters. Cosmic Spacehead is a 1993 remake of the unlicensed NES game Linus Spacehead's Cosmic Crusade, originally released in 1991. Half point-and-click adventure and half platformer, it's a game that feels utterly distinct for its time. It's also notable for its distinct art style, which echoes the great animation renaissance of the early 1990s.
