20 years after the events of XCOM: Enemy Unknown, aliens rule the planet. XCOM have gone into hiding and most of its members have left behind their past or submitted to alien rule.

Assume the role of a commander, who has been awakened from an alien stasis, along with his allies to try and regain control over Earth. XCOM 2 is a turn-based tactics game and will allow the commander to direct his squad in battles against the alien enemy to retake Earth.
