This is a world that i made as a kid with halo toys,broken ones that i made into a different thing so i can still use it ETC.
The U.S.A is invading hell. The devil who is a tall humanoid flame(there are a whole family of them like a dynasty.) Tried leading his army to earth in the last hell war but they failed and are getting invaded. There are robotic demons that fly with rockets and have a flamethrower in one arm claw on a cable that can be fired to grab. The hell empire is like a normal civilization but more hellish and stuff. The main demons either look like storm troopers or jackals from halo.
Your friends were taken as souls and you became a government contractor to kill and tear at the enemy. You were injured in battle as an elite stares over you but is shot up by others. You get extracted from the zone. (Bye bye baby blue. I wish you could see the wicked truth. Cuaght up in a rush, its killing you.)
