Checkpoint looking much like an outpost from the movie Godfather. Road signs with occult symbols depicted on them. Poisoned radioactive earth below. All of this makes you feel very uncomfortable. Your heart starts beating faster and you experience a sudden adrenaline rush when you hear even a subtle noise behind because you're always on your guard. When moving through such unwelcoming place you always expect danger. Don't you dare to set foot on the abandoned highway, it's a suicide. Every dweller of the purgatory knows that.
Ruined and twisted flyover structures with armature bending into intricate shapes or sticking like giant pins ready to penetrate you through. There was a time when this place used to be a busy speedway. Now after nuclear explosion it's completely unrecognizable, and only burned out car frames with bodies of drivers inside remind of what this place once was. Lots of bodies, lots of innocent victims who died in vain. Refusing to accept their fate they preferred to stay in this place, trapped between the world of the living and the afterlife, raging, insane, blaming everyone for what has happened to them. These beings are no longer humans.
There is danger and fear following you around in this place. Awaking the dwellers of such desperate place doesn't seem like a good idea.
