About this Mod
The Unseen Observer
All event frequencies and spawn rates can be configured in the mod CONFIG file
A psychological overhaul for Minecraft 1.20.1 (Forge). This isn't a "dweller" mod. There are no loud screams or cheap jumpscares.
Overview
The Observer is a background process that monitors player behavior. It doesn't want to kill your character; it wants to interfere with your perception of the game.
Features
- Behavioral Tracking: The entity logs your movement patterns, death count, and playtime. This data persists across different worlds.
- Metadata Integration: The mod pulls your PC hostname and OS username. The Observer will use this information to address you directly via chat.
- Environmental Gaslighting: Subtle manipulation of world triggers. Torches may extinguish, sounds may desync, and chunks may update incorrectly when the entity is "present."
- Real-time Synchronization: The mod uses your system clock to trigger events. Nighttime in real life changes how the entity behaves in-game.
Technical Notes
- No internet connection is required. All data is stored locally in a hidden
.datfile. - If you see your real name in the chat, it is not a bug. It is a feature.
- We recommend playing with headphones and at least 4 chunks of render distance.
