XCOM 2 is the sequel to the award-winning strategy game of 2012, XCOM: Enemy Unknown. The Earth has changed. Twenty years have passed since world leaders offered an unconditional surrender to the alien forces, and XCOM, the planet's last line of defense, has been decimated and scattered. Now, the aliens rule over Earth, building shining cities that promise a bright future for humanity while secretly pursuing a sinister agenda and eliminating anyone who opposes their new order. Only those living on the fringes of the world have any room for freedom. Here, a force gathers once again to fight for humanity. Always on the run, the remaining XCOM troops must find a way to rise from the ashes, uncover the treacherous truth behind the occupation, and eliminate the alien threat once and for all.
