Descend into the Labyrinthine Horror of Atrium Mortis

Dare to enter Atrium Mortis, a chilling roguelite puzzle game where observation and nerve are your only allies. Trapped within an ancient Roman hall that loops endlessly, your survival depends on identifying the anomaly – the single element that doesn't belong in each procedurally generated room. One wrong turn, one missed detail, and the Atrium will cast you back to the beginning.

Prepare to face not only mind-bending puzzles but also terrifying creatures lurking in the shadows. This is a first-person horror adventure where every decision carries deadly consequences.

Face Unspeakable Horrors

The halls of Atrium Mortis are far from empty. Silent Angels of Death drift through the columns, their very presence distorting reality. Even more grotesque entities inhabit the deeper corridors, beings that will haunt your nightmares. Learn to avoid them, or face brutal confrontations in this survival horror experience.

A Roguelite Puzzle Game Where Observation is Key

Atrium Mortis blends intense puzzle-solving with the replayability of a roguelite. Can you escape its grasp?

• Spot the Anomaly: Scour each corridor for subtle differences. A banner's shifting colors, a statue's watchful gaze, a torch burning with unnatural cold – these are your clues.

• Left or Right: Anomaly detected? The left door is your only hope. Everything seems normal? Choose the right. But be warned: the Atrium delights in deception, warping your perception to lead you astray in this psychological horror.

• Solve Intricate Puzzles: Some doors demand more than just observation. Decipher cryptic riddles, find hidden keys, and overcome intricate challenges to progress through this escape room inspired labyrinth.

• Survive Lurking Terrors: Angels of Death and untold nightmares roam the halls, punishing every mistake. Stealth and quick thinking are essential for survival.

• Permanent Progression: Death is not the end. Earn diamonds with each run to unlock permanent upgrades, giving you an edge in your next attempt. Gain Hindsight to review past errors, Foresight to predict anomaly likelihood, or wield a Radiant Sword to banish the Angels of Death.

• Conquer the Final Trial: Reach Hall 10 and face the Atrium's ultimate guardian. Only the most resourceful and courageous will survive the final test.

• Customize Your Experience: Too frightened? Disable optional jumpscares in the settings. Focus on the atmospheric horror at your own pace.
