This is a first-person shooter set in zero-gravity, where players fight for survival, fight for air inside a futuristic space colony. Players assume the roles of astronauts battling for resources after a terrible explosion has broken apart the moon. Maneuvering in jet-propulsion space suits, players use gunpowder-gas-operated machine guns to kill opposing astronauts. Players can also compromise the integrity of their opponents' spacesuits by tossing grenades, shooting air tanks, or using close-up melee attacks to cut oxygen pipes; when such strategies are employed, astronauts die instantly or are sent hurtling lifelessly into space. Realistic explosions and machine gunfire are heard throughout the game. While roaming through an asteroid mining base, players may encounter a strip club called "Zero G Spot": the club façade depicts a neon outline of a pole dancer alongside the words "Topless Freefall Acrobatics"; however, players are not able to enter—an icon reads, "Adults Only."
