Signalis (stylized as SIGNALIS) is a survival horror video game developed by rose-engine and published by Humble Games and Playism on October 27, 2022.

The core gameplay consists of third-person shooter elements from a top-down 2.5D perspective, with occasional puzzle elements. Puzzles vary from manipulating switches and dials, to searching for certain frequencies to broadcast in Elster's radio implant.

Difficulty and thematic elements are enhanced through the use of resource management as a gameplay and narrative mechanic. Elster is limited to six items on her person, including weapons, ammunition and key items for use in puzzle-solving and unlocking doors. In the fashion of Resident Evil, another survival horror series, there are safe rooms that allow the player to save progress and store their items for future use.

The game was developed by the two person German studio rose-engine, with development beginning in 2014.Additional help was brought on through external composers. The game was released across multiple platforms on October 27, 2022. Publishing was handled by Humble Games and Playism.

Aesthetically, the game pulls inspiration from the graphics of the fifth generation of video game consoles, particularly from the original PlayStation game console. The game includes a CRT mode to further mimic the effect. Additional aesthetic influence comes from more traditional artwork, incorporating The Shore of Oblivion by Eugen Bracht as well as Arnold Böcklin's Isle of the Dead into the game.  Literary influences include The Festival by H. P. Lovecraft and The King in Yellow by Robert W. Chambers. Filmic works by Stanley Kubrick, Hideaki Anno and David Lynch helped shape the narrative's themes of identity and memory in the game. Developer rose-engine also acknowledged Tsutomu Nihei's works as an influence, as well as Gantz.
