Earth has changed and is now under alien rule. Facing impossible odds you must rebuild XCOM, and ignite a global resistance to reclaim our world and save humanity. 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. Only those who live at the edges of the world have a margin of freedom. Here, a force gathers once again to stand up for humanity. Always on the run, and facing impossible odds, the remnant XCOM forces must find a way to reorganize, build a resistance, and eliminate the alien threat once and for all.
