Server-Side Horror
Server-Side Horror, a fully configurable ambient horror mod, makes a world feel cursed through subtle events that begin once a grace period has passed.
What it does
Events start after a grace period, which is three days by default. They are subtle and unsettling rather than frequent, and the mod includes only one jumpscare. A few new structures are added as well, so the horror can be found while exploring.
Operators can issue commands aimed at chosen players and set off a given event whenever they like. Because the mod is server-side, players join without installing anything, and the server can run it without the players knowing it is there. Deimos is required for the mod to run. The mod is published for Fabric, Forge, NeoForge and Quilt, with files for 26.3 released on 2026-09-26, and the license is MIT, so the code is open source.
The author built the mod for a summer modjam in 2025 and kept developing it afterward, with more events planned. Events were tuned so that each one appears at least twice in a two-week stretch of play without becoming repetitive. Public links exist for the source code and a wiki.
