XCOM: Enemy Unknown

As commander of XCOM, a secret paramilitary organization, you coordinate Earth’s defense against an alien invasion. You decide how to respond to threats around the world while balancing limited personnel and resources.

On missions, you direct a squad in turn-based battles, moving soldiers into position, using cover and abilities, and choosing when to attack or hold position. Soldiers gain experience and can be customized for different combat roles; injuries sideline them, while death can be permanent.

Between battles, you manage XCOM’s headquarters, assign research, develop equipment, expand facilities, and oversee soldiers and air units. These choices shape your ability to meet later threats, while the campaign’s global demands force you to weigh which missions and investments to prioritize.

Players often praise the combination of tactical squad battles and strategic base management, saying that careful positioning and consequential decisions make missions tense and satisfying. Many also value the attachment that grows around soldiers who can be lost permanently, and describe the campaign as engaging and replayable. Some reviews note that unpredictable misses and the steep challenge can be frustrating.
