Fear Deeps is a tense, first‑person survival horror set inside a decrepit psychiatric nursing home. The game begins when you wake up and find a desperate letter from Lily - a former nurse who was expelled after a mistake and later imprisoned by the dean after discovering disturbing experiments. You must follow her final plea and navigate the madhouse, searching for keys and clues, opening the basement door and reaching Lily’s trapped room - all while avoiding horrific, patrolling monsters.
