XCOM - Vigilant

It's been twenty years since Earth lost the war against the extra-terrestrial threat. XCOM Headquarters was destroyed, its personnel killed and imprisoned.

Now, the ADVENT Coalition rules the world, a human government controlled by the aliens. They have crushed all attempts of resistance against them, managing to find different resistance havens and obliterate them.

But there is still hope.

Some of XCOM's operatives managed to fight their way clear of the alien assault on XCOM HQ all those years ago. With them, John Bradford, or 'Central', and Chief Engineer Shen escaped, fleeing into the wilderness. They've been operating in the shadows since then, from their new mobile headquarters, the Avenger, a commandeered alien transport. Now, as ADVENT is becoming increasingly active, they have decided to come out of the darkness. XCOM fights again.

The war isn't over. Remain Vigilant.
