Enviroment

So the enviroment for Underworld is basically just supposed to be post-apocolyptic. Underworld is all about someone living their life in a bunker away from the city for safety, but the world itsself isnt safe either. Sometimes a gas mask might be needed, or a gun but what we dont know is if the enemy is just other humans or if it might be something not human. Everyday is a fight for survival.
