Arch Angelo Ghost Hunter I: 'Serviam'

This is a story of an ex-Marine Captain Arch Angelo who was involved in a fire-fight in the mountains of Afghanistan. Unknown to him the enemy leader of the ambush party Khalid bin Abu Rabi and his evil followers who were all killed that day return as avenging spirits to track down Arch and the four men on his team. His men are immediately possessed by the spirits but for whatever reason that they could not fathom at the time they could not do the same with the leader of the Marine team. The men are all separated after their service ends. Arch suffering from Post Traumatic Stress Disorder is tracked down in a remote area of Nevada by his demonic possessed men. To their surprise they find that Arch has been transformed into a being of unlimited powers with the help of a psychic madam who runs a local bordello. Khalid uses his demonic power to build a vast army of coy-wolves possessed by demons from hell. A great battle ensues but in a surprising turn Satan himself teams up with heavenly forces to defeat Khalid and his followers but at a cost. Death gives rise to Arch Angelo as not only the avenging hand of God but of Satan himself.
