Horror Nights Story is a survival-horror game structured around five nights: each one sends monsters — ghosts, bats and worse — while you dig and solve puzzles toward an escape. Progress carries between nights, so what you accomplish early makes the later ones survivable.
The five-night structure gives it a clear arc rather than an endless grind, and the digging gives you something to do beyond hiding.
Five, each harder than the last, with your progress carrying between them so early productivity pays off later.
It's a monster-survival horror game with jump scares rather than gore, aimed at teens and up.
