Iron Door is a tense survival horror game where every shadow hides a nightmare, and every locked door holds a secret. Trapped inside a decaying sewer system, you must fight, solve, and survive as you uncover the terrifying truth behind the horrors lurking within.

Survive with whatever weapons you can scavenge—every bullet counts, and every encounter could be your last. Resources are scarce, so use them wisely.

The deeper you go, the darker the story becomes. Solve environmental puzzles and search for hidden clues. Explore multiple levels of the sewer, each more treacherous than the last. Eerie corridors, flooded chambers, and abandoned maintenance rooms hide valuable resources and lurking dangers.

The Watchers and the Listeners: Two terrifying entities stalk the sewer, each drawn to different senses. The Watchers have a massive, unblinking eye for a head, their bodies grotesquely fused to industrial lights. They scan the darkness, searching for movement. Step into their glow, and they'll come for you instantly. The Listeners, by contrast, are blind, with a single grotesque ear where their head should be. They are attuned to every sound—make too much noise, and they'll hunt you relentlessly. To survive, you must master light and silence, or risk falling prey to the horrors that dwell within.

Can you escape before it’s too late?
