Mundaun is a 2021 first-person horror game created by Swiss developer Hidden Fields and published by MWM Interactive.

He is told that his grandfather died in a barn fire, and was already buried, but when visiting the building's ruins he finds a burned corpse.

[4][5] Mundaun started development in 2014, through concepts made by the lead programmer and artist, Michel Ziegler.

The introduction of MWM Interactive as a publisher allowed additional funding, writers, programmers, and sound designers to join the project near the end of development.

[13][14][15][16] In a positive review for Polygon, Cass Marshall praised the game's horror atmosphere, and how the hand-drawn art style helped create discomfort.

[21] GameSpot's Andrew King enjoyed the game's means of travel, mentioning that "traversing the mountain in all these different ways--on foot, by sled, by truck--has the effect of making the mountain feel like a real place; a peak that must be considered to be conquered".

[19] While enjoying the atmosphere of the game, Nintendo Life felt the game did not translate to the Switch well, "There's metric ton of ugly pop-in, it’s often easy to get turned around by how shimmery and samey things look, and we struggled to find pivotal items because they quite simply blended in with the scenery".

Stewart was more mixed on the game's story decisions, commenting that "They don't hurt the narrative, but the choices are boilerplate and feel tacked on.

"[4] The Washington Post liked Mundaun's use of non-Euclidean geometry to confuse the player, "Spaces dissolve and connect in mildly startling ways — something I’ve always thought more developers should make more use of since games are a wonderful medium for inducing disorientation".
