XCOM 2 is the sequel to XCOM: Enemy Unknown, the 2012 award-winning strategy game of the year. Earth has changed. Twenty years have passed since world leaders offered an unconditional surrender to alien forces. XCOM, the planet’s last line of defense, was left decimated and scattered. Now, in XCOM 2, the aliens rule Earth, building shining cities that promise a brilliant future for humanity on the surface, while concealing a sinister agenda and eliminating all who dissent from their new order.
