About This Game
A first-person cosmic horror short experience set in a hallway-style map, where you uncover the secrets of an abandoned facility while being stalked by a mysterious entity
Detailed Description
Project Mortuus Astrum is a short first-person cosmic horror experience set in a decaying, labyrinthine facility. You awaken alone, disoriented, and pursued by an unseen entity.
Explore claustrophobic corridors and abandoned rooms as you uncover environmental clues and solve spatial puzzles to unlock new areas. The game features a hallway-style map design focused on tension and atmosphere, with dynamic audio cues and visual storytelling.
There is no combat—your only tools are observation, memory, and movement. The entity stalking you reacts to sound, forcing you to adapt your exploration strategy. The experience lasts approximately 10-15 minutes.
Will you escape the facility… or become part of its forgotten history?
