Prehistoric Dweller
by Swayle
With Prehistoric Dweller, a cave-dwelling horror monster stalks players who explore underground, pushing the original Cave Dweller into a far more frightening range.
What it does
The mod adds a new cave monster for Forge that is meant to be far scarier than the original Cave Dweller. Its behavior is unpredictable and each encounter is intense, so the creature keeps the player on edge for the whole time spent underground. Light sources can be put out by it, and it can scale cave walls and cross open ground to track the player. The Prehistoric Dweller runs on client and server, so the server and every player need the mod installed. Builds are published for Forge 1.20.1 under the MIT License, but the code is not open source.
