In the 20 years that have passed since Earth’s leaders surrendered, the planet has changed beyond recognition.
On the surface, our alien overlords have built shining cities, promising a new future for mankind.
But this new order tolerates no dissent from its human subjects, eliminating any who speak out against its sinister agenda.
But from the remnants of XCOM, a resistance is building; a force who exist on the margins of society,
fighting from the underground to build popular support, expose the alien’s terrible plans and strike back
against the deadly threat once and for all.
From your mobile command centre, traverse the globe and guide your strike forces into battle against
the extraterrestrial enemy.
Mobilise highly trained Rangers, Grenadiers, Sharpshooters, PSI Operatives and combat specialists
in tactical manoeuvres against well-equipped foes.
Take on alien war machines and the elite soldiers of ADVENT – the aliens’ personal police force – in combat
situations where planning, teamwork and extreme force will be humanity’s only shot at victory.
