Heavy Nova

is a 1991 video game for the Sega CD, Sega Genesis, and X68000 that combines elements of fighting games with platform games and mission elements. 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. A sequel, Black Hole Assault, was released in 1992. Plot Sometime in Earth's future, it came to humanity's realization that the Earth's natural resources were starting to decline, but despite every nation's attempts, the Earth's environment and resources continued thin. Suddenly, an alien race appeared in the Solar System. Hailing from the planet Akirov, the aliens had been observing Earth for centuries and arrived in order to save it. With their technological help, Earth's environment was replenished and Humans were able to travel deeper into space. By the year 2102, humanity was finally at peace thanks to the Akirovians. Ten years later, a plot to enslave humanity was discovered to be a part of the Akirovian's plans and a war waged between the two. Eight years later, the Akirovians lost and left the Solar System. The primary machines for Earth's victory came from original Akirovian designed machines: giant remote controlled robots first used to design and repair Earth's satellite and colony structures. The robots were favored as Earth's primary line of defense and were dubbed the Heavy D.O.L.L's (Defensive Offensive Lethal Liberator). Now taking place in 2120, the prospect of earning the highest combat ranking for a Heavy D.O.L.L, the rank of Heavy Nova, has become a long desired military rank. The player assumes the role of such a person attempting to earn that rank who must go through training and combat situations to prove their abilities.
