About This Game

Atrium Mortis is a psychological horror roguelite. Outsmart terrifying entities, collect power-ups across runs, and solve high-stakes minigames - from Red Light, Green Light to zero-g space parkour. Turn off jumpscares anytime in settings.

Survive the Nightmare

• The Angels of Death - Looming heralds that patrol the corridors, waiting for you to slip up. Keep your eyes on them.

• The Face-Hiding Girl - A sorrowful spectre who dreads being seen. Never look her in the eye, no matter what.

• The Tall Man - A silent stalker in the dark. If he visits you, there is almost certainly nothing you can do.

• Stranger things lurk beyond - Entities you can’t yet name, but will come to fear.

Puzzles in your path

Solve hidden-object time trials, locate a key with a metal detector, catch Faye the Fairy, or outwit The Riddlemaster - and much more.

A Roguelite Puzzle of Observation and Nerve

• Spot the anomaly – Coins turning into ducks. A knight turning to face you. A torch burning green.

• Power up - Collect items and stack power-ups, like dice which reroll the current anomaly, or a clock that slows down time.

• Grow Stronger with Every Run - Your journey is never wasted. Earn diamonds to unlock permanent upgrades. Like Hindsight to review missed anomalies, Foresight to glimpse anomaly odds, or a Radiant Sword to strike down Angels of Death.

• Conquer the Final Trial - Hall 10 holds the Atrium’s ultimate guardian. Only the strongest souls will survive what waits there.

• High Replayability - Test your reflexes and build strategy as you unlock deeper secrets with every attempt. There is a lot more to the Atrium than meets the eye.

• Optional Jumpscares - Too scared? Turn them off in settings.
