From the back of the book:
The world has ended.
Humanity continues in its death throes. Pockets of civilization fight to regain control, taking land and power away from daemons and nightmares.
It is the year 2299. Europe.
God's chosen soldiers fight to loosen Hell's grip, battling kultist minions and daemonic half-breeds. Both ancient and the naive struggle in the battle to control the Earth plane.
The Roman Army and the Vatican have joined forces to gain command over the European nations. Unfortunately, corruption spreads deep, and the other nations pledge allegiance only to themselves.
The time has come. The battles anticipated. The Shadow Nations prepare for the final apocalypse.
