Walk the abandoned caves under the cursed city of the Wastelands. Damp dripping in the background. Maybe a swamp or below the town sewers. Dark evil dreams. Slime and toxic fallout with the stench of rotten corpses and a mix of dangerous chemicals. Mutants and/or zombies or alien monsters sneak arond the corners. Darkness, and mist floats through the streets. Spooky background music for a film or a video game. Variants: Loop and No-Drums Loop.
