Halo Of Wonders
Millions of demons have tasted your heavy metal in the deep, dark corridors of Phobos. Each demon killed has been sent to a reviving facility created by the demons themselves, and one by one, the demon count increases. Day by day you slaughter over a thousand demons and on those days, they are sent to the facility.
