Description (by MicroProse Software)

"This is an addictive strategy game that pits you against aliens terrorizing the Earth," said Carl Knoch, product manager. "You must command groups of scientists, engineers and soldiers as well as develop a strategy to ensure human survival."

As commander of X-COM, which is a covert organization formed by the world's governments to investigate and defeat the alien invasion, you:

  • Intercept UFOs as they sweep across the Earth
  • Track all alien activity on the Geoscope rotating globe display
  • Plan a strategy for research and manufacture of captured technologies
  • Take charge of tactical operations in the 3-D isometric Battlescope display
  • Investigate UFO crash sites and alien bases
  • Monitor the political situation
  • "To really see the aliens come to life, turn off the lights because the bold colors and graphics show up even more", said Knoch.
