A countdown to assimilation. A faction in need of a real leader. A mission to unite a warring world one way or another.
Aidan Steele is a military veteran who lives an unfulfilling post-service life as a cog in the military industrial complex. When an old friend offers him the chance to return to duty, Aidan jumps at the chance to relive the best years of his life. He thought it would be just another tour of duty, but he couldn't have been more wrong.
The System created the perfect battlefield. A single super-continent called Novopangea that holds every nation on Earth. Advanced alien technology is rewarded for every victory and even allies have an incentive to betray their former partners for a chance to remake the world in their image.
In a place filled with advanced alien technology, fantastical monsters, warring factions, and a countdown to destruction, success is anything but guaranteed. As a System Envoy, Aidan has been given a mission: Build a faction, unite the planet before the countdown runs out, and prepare to defend the Earth from the other species in the galaxy who have been successfully assimilated.
This isn't the world's deadliest game, it's a System.
