About X-COM: UFO Defense
X-COM: UFO Defense (also known as UFO: Enemy Unknown) is the 1994 strategy masterpiece that defined the tactical alien-invasion genre. You command X-COM, a multinational organization defending Earth from alien invasion, juggling two layers of gameplay. The strategy layer is a global simulation: you manage bases, research alien technology, build aircraft, and respond to UFO sightings and terror attacks around the world. The tactical layer is turn-based squad combat, where your soldiers — with ranks, skills, and equipment you equip — fight aliens in destructible environments. The game is brutally difficult and unforgiving, but that is part of its legend: every soldier death is permanent, and losing a country's funding can doom the planet. Its depth and tension influenced countless games, including the modern XCOM reboots and many others. It remains one of the most influential strategy games ever made.
