X-COM: UFO Defense is a strategy game that combines tactical combat with base management and global defense.

Players recruit and train soldiers, build bases, and develop new weapons and equipment based on recovered alien technology. Missions involve turn-based combat against aliens in various environments, with permadeath adding tension to each engagement. As the alien threat escalates, players must balance research, defense, and offensive operations to protect Earth's nations from panic and alien infiltration.
