Overview
X-COM: UFO Defense (1994) was MicroProse’s strategy game that brilliantly combined turn-based tactical combat with strategic base building. Players defended Earth against alien invasion across two interlinked layers: managing global operations and commanding squad-level combat. Its punishing difficulty and emergent storytelling created legendary gaming experiences.

Legacy
X-COM established the template for tactical strategy games. The 2012 reboot (XCOM: Enemy Unknown) proved the formula still worked, and “XCOM-like” became a genre descriptor. Julian Gollop’s design principles remain influential.
