Lightspeed DOS

Lightspeed is a video game developed and released by MicroProse in 1990. It features a space flight simulator game and action game elements with an emphasis on strategy and exploration. The box describes the title as an "Interstellar Action and Adventure" game. The game features space exploration, trade, combat and diplomacy in the same vein as 4X s such as Master of Orion. Lightspeed, unlike the popular series of turn-based strategy games, plays out in real-time.

A sequel, entitled Hyperspeed, was released by MicroProse in 1991. It was nearly identical to Lightspeed, except that it included two additional star clusters for veterans of the first game.
