A horror map in large suburbs that feels eerie because of its emptiness (with empty parkings, boring houses that feels copy-pasted, things like that, kind of common in american suburbs)
The main scary thing would be its emptiness and lack of people, a liminal-like feeling, and some things that aren't regular, like some things written on the walls like "the end is near" (you can use
minecraft heads for the letters)
(There would be no light in houses and everything would feel extremely regular; no paintings, nothing special in houses, always the same pattern of house, no trees in the streets, the grass would be flat, etc)
