About X-COM: UFO Defense
X-COM: UFO Defense puts you in command of X-COM, an organization formed by the world's governments to fight an escalating alien menace. You lead the effort to combat the alien forces and save Earth, while keeping an eye on world politics and the funding that governments provide.
Ground assault missions
Shooting down a UFO is only the start. You then lead a squad of heavily armed soldiers across different terrains to investigate its crash site and recover useful technology, weapons or life forms. Your squad can use automatic rifles, rocket launchers and tanks against the aliens.
Research and manufacture
After successful ground assaults, X-COM's scientists can analyze alien items. Each breakthrough helps them understand the technology and culture of the alien races. With enough research into the superior weapons and crafts used by UFOs, X-COM can manufacture weapons of equal capability.
Political decisions
You make crucial decisions as you fight the alien forces, while monitoring the world political situation. Governments may enter secret pacts with the aliens and then reduce X-COM's funding.
