Quake Minus One is a real-time strategy video game published for the Commodore 64 by Monolith/Beyond in 1985 and was written by Warren Foulkes and Mike Singleton.

In the 1980s, the Western world constructed a large power plant named Titan under the Atlantic Ocean in order to extract geothermal energy from the Mid-Atlantic Ridge where the Earth's crust is thinnest.

Members of the Robot Liberation Front invade the power plant and seize control of the robots demanding equal rights for the machines, failing which they would use the power plant to trigger a massive earthquake which would severely threaten America, Europe and Africa.

Titan is under the control of five separate AI computers - Zeus, Poseidon, Vulcan, Ares and Hermes.

There are also quake suppression buildings to protect which if destroyed, bring forward the game's deadline.
