Millenium: Return To Earth is a strategy game, in which player commands human colony on the Moon. Gameplay focuses on colonizing other planets, gathering resources and building starships.

A month ago you were a lunar research chief, collecting data from a minor base on the moon's surface - doing your job. At first no one believed that Earth was doomed, but it came, just as they had predicted. You and your party had a ringside seat to unspeakable destruction and chaos. Now, in the shadow of the blackened husk that was once Earth, you plan your strategy for saving humanity not as a scientist, but as leader of the juman race.
