Mission: Empire!

Mission: Empire! is a 1-player science fiction themed strategy game for the TRS-80 CoCo.

The time is the far distant future. Man's first galactic empire has collapsed into chaos. After many generations, you are going to try to establish a new empire in this region of the galaxy. The fleet you inherited from your father last year is ready.

The player starts in Year 1, and the goal is to conquer all 20 in the sector within 1000 years. The player receives a final score for conquering all 20 planets and the time required to do so. There are 2 levels of difficulty. From command mode, the player can attack other planets, build/tax their population, scout nearby and distant systems, sleep, and travel. The player and their fleet travel as bulk between planets, and orders can only be given to the planet currently occupied.

The player can build 5 units/year, consisting of naval squads, marine cadres, and scout ships. Multiple years of production can be planned in advance. These units can then be sent to other planets for pickup. Unattended vessels and units will only last for 6 years before being forfeited. The central computer allows viewing and calculating distance to other planets. Scouting nearby and distant stars allows gathering further details including the strength level of these planets. Sleep allows time to pass to build up forces. Travel between stars also uses a period of time. During combat, the player is given a probability of victory, and chance of success changes as troops are destroyed until a combatant reaches 100%.
