About Prison of Nightmare
Prison of Nightmare is a single-player, first-person psychological horror game. You explore the protagonist’s dreams, solve puzzles and try to escape an ancient spirit that has invaded their sleep to capture their soul and trap them in an eternal nightmare.
The nightmare
The spirit twists the protagonist’s dreams into distorted, terrifying landscapes. Environments change suddenly and anomalies appear without warning. The entity can summon frightening apparitions and alter the dream world as it relentlessly pursues the protagonist.
Explore and survive
You navigate the dreams, solve puzzles to progress and uncover the story behind the dark entity. The game combines exploration, puzzle-solving and survival elements; you must keep a clear head to find a way out of the nightmare. Realistic graphics, advanced lighting effects and three-dimensional sound design shape the experience.
