Earth didn’t stand a chance. Our story begins hundreds of years in the future, after alien invaders hellbent on claiming this planet as their own poured out of the Stormgates and brought an end to the world as we knew it. Yet humanity survived.

As the fully-playable demonic Infernals and high-tech Celestial Armada return to unleash havoc once again, Earth’s defenders must gather their courage—and climb into their 20-foot tall mechs—to save the world. It’s up to you to pick a side, harvest resources, build your base, and command mighty armies to decide the outcome.
