Heavy Nova is a video game for the Sega Mega-CD, Sega Mega Drive/Genesis, and Sharp X68000 that combines elements of fighting games with platform games and mission elements. It was released in 1991 and distributed to Japan and the United States and quickly became known as kusoge. Players assume the role of a robot operator destined to earn the highest operator rank. To do so, the robot – known in the game as a Heavy DOLL – must complete a combat training camp which prompts the 2D Platformer stages. The player then must combat other Heavy DOLLs as the end-level bosses which prompts the 2D fighting elements.
