Humanity has kept to remote bunkers amidst the chaos.
Supplies are always low, and lives are often cut short.
The ground layer of Earth is inhabited by soulless demonoid creatures of unknown origin and have hunted humanity near extinction.
The inhabitants of the Emerald City have banished the refugee to the holding cells, left with a pistol to end his misery.
As he stares down the barrel, the bunker is over run.
Now the refugee has an option!
To die, along with the others, or to fight to find the daylight of another morning.
