The game uses standard horizontal shooter mechanics but differentiates itself by offering a different level of intensity and difficult game play. The player must brave eight rounds of space, insect, and mechanical worlds before defeating the final enemy, each world more difficult than the last. The player is also offered three modes: easy, normal, and hard to play, as well as a scoring system for replay-ability.
Round 1: An outer space battle begins. The ship must overcome a line of missile launchers and defeat the first boss.
Round 2: An alien battleship must be defeated.
Round 3: The ship scales a giant vertical structure and must defeat the structure's mainframe at the top.
Round 4: The ship has entered an alien world. A mechanical robot boss must be defeated.
Round 5: An electrical world that houses many strange electrical enemies including a long-armed electrostatic mini-boss and a mechanical boss.
Round 6: The ship must battle a gigantic eye monster.
Round 7: The ship must battle a giant green brained monster with dangerous claws.
Round 8: The final battle over a planet that closely resembles Earth. The final boss takes on two forms and must be fought twice.
