Eclipsium is a 2025 surrealist horror game developed by Housefire Games and published by Critical Reflex.
Eclipsium is a first-person horror game in which the player explores surreal environments while making their way towards a distant tower with a prominent floating heart.[1] It features bizarre symbolic imagery and a string of horror concepts incorporating elements of surrealist, cosmic, and body horror.[1][2]
Described as a walking simulator, its gameplay primarily derives from following a linear path through a series of different areas, although there are some simple puzzles included throughout the game.[3][4] As they progress, the player character sacrifices various parts of their body to attain special powers in their hands; these are often used to solve the game's puzzles or to interact with the environment.[1][3][5]

Eclipsium was developed by Gothenburg, Sweden-based[6] studio Housefire Games and published by Critical Reflex.[3] A demo was released in 2024[7] followed by an updated demo on 28 August 2025 to coincide with the announcement of the full game's release date.[8][9] The full game was released for Steam on 19 September 2025.[10]
