Empire

About

Empire was one of the first multiplayer space games, written by John Daleske for the CDC PLATO system in 1973. This single-player recreation pits the Federation, Klingons, Romulans and Orions against each other in real time, rendered in PLATO's plasma orange.

Pick your empire, up to three rivals, allied bots and a difficulty from Cadet to Admiral. Bomb enemy worlds, beam up armies from your own and beam them down to capture. Win by wiping out every rival, or by holding a share of all worlds long enough.

• Five difficulty levels you can change mid-game
• Each race flies a different hull, from strong and slow to fast and fragile
• Optional fleet growth: hold more worlds, field more ships
• PLATO-style typed commands alongside mouse and keyboard controls
