Supremacy: Your Will Be Done – MS-DOS cover art Supremacy: Your Will Be Done is a science fiction strategy game developed by Probe Software and released for MS-DOS in 1991. Also known as Overlord in North America, the game puts players in command of a growing interstellar empire competing against a powerful alien adversary. Starting with a single inhabited planet, players must explore and colonize new worlds, develop their economy, and build a military force capable of conquering an entire star system.

The gameplay combines resource management, planetary development, and strategic warfare. Players must terraform planets, establish agricultural facilities, construct energy-generating satellites, and maintain a steady supply of fuel and resources. Expanding colonies generate tax revenue, allowing players to purchase spacecraft, defensive weapons, and military equipment. As the opposing empire grows stronger, players must carefully balance economic expansion with military preparations, eventually launching attacks against enemy planets and heavily defended starbases.

Featuring colorful graphics, a mouse-driven interface, and four increasingly challenging star systems, Supremacy: Your Will Be Done offers an engaging blend of accessibility and strategic depth. Its distinctive combination of economic simulation and interplanetary conquest helped it stand out among early 1990s strategy games. With its futuristic atmosphere and emphasis on careful planning, it remains a memorable example of classic space strategy gaming from the MS-DOS era.
