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.

Heavy Novas Single Player game play is separated into two sections: a platform game section and a fighting game section. The player has to destroy every possible enemy robot in the Platformer sections and make it to the end in order to fight the boss awaiting them. The player has various attacks at their disposal with the Idar, most of which they were able to use during combat with the bosses in the Fighting Game stages. During the Fighting Game Stages/Boss Fights, the player had to defeat the boss using various Fighting Game attacks such as a button command that allowed missiles to launch from the Idar's hand. However, both Heavy D.O.L.L robots, player and enemy, has an energy bar under their health meter; the energy bar measures how much strength the player or enemy has in order to move their robot. Taking too much damage results in energy depletion. When the player's energy was depleted to two bars, the player robot cannot move, leaving the player completely vulnerable to enemy attacks. Alternatively, the 2 Player mode pitches two players against each other using all of the enemy robot models encountered in the game.
