Moonrace is a top-down shooter whereby players control a cannon-equipped bipedal walking machine on the moon, battling against AI(artificial intelligence) foes. The setting for this game is a future where humans have been merged with AI. The few remaining humans who have continued to resist the AI now live on the moon, where they plot an armed uprising against the AI-fused people living on Earth. Play as a member of the guerrilla troops, riding the mecha MS-2(Moon Suit 2) in the battle against the AI.
The MS-2 walks slowly, and the single button control of the cannons are not easy. The terror and intensity of battle is conveyed through the difficulty of these controls.
