High Frontier

High Frontier is a turn-based strategy game centered on the development of America’s Strategic Defense Initiative. You oversee research and development, assign money and staff across six components, and manage the activation of defensive units.

The game uses an icon-based control system with six decision screens. Research & Development handles project investment, while the Shield screen is used to launch operational SDI units once the required permission codes are available. Espionage and reconnaissance provide information about enemy development, though their reports may be imprecise. The Threats screen tracks enemy resources and moods, and the World screen advances the game through time.

Released in 1986, High Frontier was developed by Software Studios and published by Activision and Activision (UK) Limited for Amstrad CPC, Commodore 64, Commodore C64/128/MAX, and Sinclair ZX Spectrum.
