Uncanny
by Denmoth
Uncanny is a Forge horror mod for Minecraft 1.20.1 in which the game begins to break its own rules, with fake crashes, phantom players and rendering errors.
What it does
Uncanny is a psychological horror mod that breaks the fourth wall. Its scares come from the interface and the world rather than from monsters alone: visual glitches, corrupted UI elements, dead pixels, inverted controls and messages in chat from players who are not actually on the server. An entity called a rendering error can appear as a corrupted texture mapping, and footsteps may sound behind the player.
The mod runs on the client and the server, so both need it installed. Its behavior is shaped by a trust system, a First Anomaly that begins the sequence, and a watcher that tracks the player's distance and ends the connection if the player gets too close. Torches can be extinguished for a reason, which the mod does not explain at once. Every part of the experience is adjustable through a config file, from a subtle unease to a full nightmare.
Uncanny is open source under the MIT License, and the source code and issue tracker are public. Forks and addons are allowed, which means modpack makers may build on it. Only the Forge loader is covered, and the single published file is 0.1.0 for 1.20.1, released on 2026-01-07 on the beta channel.
Key features
Fourth-wall breaks
The game addresses the player directly through chat and the interface, making the scares feel like part of the world.
Visual glitches and fake crashes
Dead pixels, inverted controls and corrupted UI elements appear during play, with crashes that are only simulated.
Phantom players
Chat messages can come from players who are not on the server, and a rendering error entity can appear in the world.
Trust and distance
A trust system and a watcher that measures distance decide how the anomaly progresses, and getting too close ends the connection.
Configurable intensity
A config file lets server owners and players adjust how subtle or intense the horror is.
