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. This video review features video gameplay footage of Cosmic Spacehead for the SEGA Genesis and audio commentary from Classic Game Room's Derek.
