Millennium 2.2 title screenshot
Millennium 2.2 is a resource management computer game by Ian Bird, released in 1989 for Atari ST, Amiga and DOS. The DOS version of the game was released as Millennium: Return to Earth. It is the forerunner to Deuteros, which is in many ways a similar resource management game but many times larger and harder than 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 humankind 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.
The only break from the resource management simulation comes when the player is under attack by Martians. Combat is represented with a space ship fighting mini-game with basic 3D graphics. Initially the game is a race against time as each attack is heavier than the previous. The player eventually must find the necessary technology to attack Mars to make the attacks cease, establish a base there, and while there discover the terraforming technology.
The player needs to balance manufacturing output with the available solar power, and many minerals are only available from certain planets or asteroids. Depending on planetary orbits, colony ships and probes can take longer to reach their destinations. As time progresses, colonists will adapt to different atmospheres, and after Earth is terraformed, secede from the player's control (this event will also strand any of player's ships that may be docked on those planets).
In the DOS version, resources are largely randomized for different planets, as is atmosphere determining if mutations occur, with notable exceptions of Earth, Mars and Luna.
Millennium Remake 1.21 is a remake of the original Amiga game published by Electric Dreams. With the rich resources of the solar system at your disposal, you must defend your colony against hostile attacks while ultimately trying to discover how to recolonize Earth and ensure the survival of the human race.
