X-COM: UFO Defense

About the game

X-COM: UFO Defense (UFO: Enemy Unknown in Europe) welds two games together and makes each better. On the Geoscape, you run a clandestine agency defending 1990s Earth: placing bases, launching interceptors at UFO contacts, researching recovered alien tech and begging funding councils not to defect. On the Battlescape, every crash site becomes a turn-based nightmare — soldiers with time units, snap shots and shaking morale advancing through farmland and cornfields toward things they can't see.

The tension between layers is the engine of the drama. Autopsy research unlocks laser rifles your rookies will die carrying; a terror mission failed on the strategic map means a city panics and a funder walks. Soldiers are fragile, named and permanent — the sergeant who survives five missions becomes irreplaceable, then a Chryssalid finds her anyway, and the memorial wall grows.

Julian Gollop's design (published by MicroProse) is regularly voted among the greatest games ever made, and its DNA — permadeath squads, research trees, interlocked strategy and tactics — powers a whole modern genre of successors and remakes.
