Cosmic Horror

Players spawn into a world that starts out ordinary but gradually becomes stranger. Unseen entities linger just outside perception, creatures watch from places that should not exist, and the moon and time can behave wrongly. Darkness is treated as an absence of light, and hidden mechanics respond to what the player does and what surrounds them. More than ten unique events occur naturally during play, and rare encounters grow more unsettling the longer a player survives.

The mod is built around a hidden story about the disappearance of humanity. Secrets, lore and mysteries are placed for players to find as days pass and the world becomes increasingly unnatural. Jumpscares are unpredictable and used sparingly so that the player stays on edge. The design draws on the cosmic dread of early twentieth-century weird fiction and is meant for single-player play. It is released under All rights reserved and is not open source.

Installation needs Cloth Config API on every loader, and Fabric API on Fabric. Only the player's game needs it, and servers run without it. Builds exist for 1.20.1, 1.21.1 and 26.1, with the latest Fabric and Forge file at 1.0.0 for 1.21.1 and the latest NeoForge file at 1.0.0 for 26.1.
