XCOM: Enemy Unknown

A turn-based tactical strategy game with resource management elements, developed by Firaxis Games as a reboot of the 1994 classic X-COM: UFO Defense. The player leads the international XCOM organization, tasked with defending Earth from an alien invasion. The gameplay combines strategic base management, where players research technologies, train soldiers, and construct new facilities, with tactical turn-based combat, where XCOM troops battle against extraterrestrial forces. Every decision impacts the balance of power, and soldier deaths in combat are permanent. The game was praised for its deep strategic elements, high difficulty, and replayability. XCOM: Enemy Unknown was released on Windows, macOS, PlayStation 3, and Xbox 360, later adapted for iOS and Android.
