XCOM: Enemy Unknown places you in command of a covert paramilitary organisation called XCOM, tasked with repelling a terrifying worldwide alien invasion. As commander, your responsibilities span managing resources, advancing new technologies and directing both overarching combat strategy and the tactics of individual units in the field. This is a strategy game that reimagines a title widely regarded as one of the finest ever made, rebuilt by the experts at Firaxis Games with an entirely new invasion narrative, fresh enemies and new technologies to develop against the alien menace.
Control of humanity's fate flows through several connected layers. You research captured alien technologies, construct and manage a fully operational headquarters, plan combat missions and command soldiers directly on the battlefield. The strategic side lets you recruit, customise and grow unique soldiers while detecting and intercepting the alien threat, and it pairs turn-based tactical combat with dramatic action sequences and ground-level fighting. Air units such as the Interceptor and Skyranger extend your reach, and the campaign carries the conflict across the globe through more than 70 unique missions that involve interacting and negotiating with governments worldwide, making it a substantial strategy experience on PC.
