Caverns of Darkness

The final rift was closed and the Hell War was over at last. The citizens of the Earth celebrated for the first time in almost six years. The forces of Hell had been beaten. Humanity had won. Now began the long process of burrying the dead and rebuilding, but the nations of Earth were united now, and they were willing to work together to usher in a golden age of peace. However, all was not as well as it had seemed, for six months later, more Hellspawn began to appear and the air was once again heavy with cries of pain and screams of death.

They literally came out of nowhere, biting and snarling, and no matter how many you and the others blasted, more seemed to fill the gaps. When ammo was running low, you and the other marines took cover. Somehow, you got separated from the others, and when all was quiet, you came out to see what had happened. Of the Hellspawn and your buddies, there was no sign, except for a trail of blood leading into the mines. With the sun setting red at your back, you stood looking at the mine entrace which under the fiery glare looked like the gaping maw of some Hellish beast waiting to devour you alive.
