Nightmare House: The Original Mod

You are trapped in Nightmare House, where a haunting presence follows you as you try to escape. The story moves from a terror-filled house into the eerie halls of an abandoned hospital.

Explore dark corridors, search for ways forward, and uncover the mystery behind the places you visit. The campaign is mostly linear, with occasional environmental puzzles and staged scares along the way.

Fight undead with firearms and a melee axe, and encounter allied soldiers during parts of the journey. The story-driven campaign offers two possible endings.

Players often praise the oppressive atmosphere, eerie level design, and sound, saying they make the short campaign memorable and unsettling. Many also enjoy being able to fight back with guns and an axe, alongside the mix of horror and action. Reactions to the jump scares vary: some find them effective, while others consider them repetitive or predictable.
