Halley's Comet

Released by Taito for arcades in January 1986, Halley's Comet represents a culmination of the technical expertise of its time. During the development of this title, a technical inconsistency was identified regarding the layering priority between the high-score display and the background graphics. This glimpse into the constraints of the development environment at the time serves as an intriguing record for the history of technology.

Unknown alien life forms released from Halley's Comet as it approaches the solar system have begun invading several planets that serve as Earth's colonies. Players must pilot an armed spacecraft, orbiting each planet to eliminate these life forms while making their way toward the comet. A battle unfolds to defeat the encroaching enemy and restore peace to the solar system.
