Millennium 2.2

In the game, humanity has colonized the Moon and Mars. However, a 20 trillion ton asteroid has collided with Earth, making it uninhabitable. All that is left of humanity is a small, self-sufficient colony on the surface of the Moon, and a race of mutant humans on Mars. As the commander of Moonbase, it is your job to ensure the survival of mankind by exploring the Solar System for other habitable planets and moons, and ultimately re-establish life on Earth. However, the Martian mutants consider themselves the superior race and want Earth for themselves, meaning a war is inevitable.

The core of the game is spent in resource management and researching new technologies for space ships and base improvements. At first it is possible only to mine asteroids before a suitable planetary colony can be discovered and established. A typical game involves manufacturing probes, maintain defenses to fend off the Martian attacks, managing each colony's solar power energy generation, mining for resources on various planets and their moons and control the traffic to and from the Moon. Out of fifteen ingame resources, only silver, uranium, and chromium cannot be obtained by mining the Moon or Asteroid Belt.

In the July 1989 edition of Zzap!, Robin Hogg called this "an exceptionally compelling game." He did think the game could be completed relatively easily in about 20 hours, but nevertheless found it addictive. He concluded, "A little slow to start with, Millennium quickly becomes engrossing with interesting problems all the way and is easily the best looking strategy cum adventure game for a long while."

In the September–October 1989 edition of Games International (Issue #9), Kevin Warne called this "an incredibly addictive game." He gave both the game and its graphics above average ratings of 4 out of 5, saying, "It remains, after Dungeon Master, the best game I've purchased in a long stretch, and I thoroughly recommend it."
