online horror adventure
Online Horror adds a dangerous biome, a boss and a set of creatures to the world, each drawn from internet horror legends, for players who want exploration to carry real risk.
What it does
The mod adds a new Online Horror Biome that generates in the world. Its terrain is dark and horror-themed, with broken phones scattered across the ground and torn notes to find. Hostile creatures spawn naturally throughout the biome, and the area is built to unsettle anyone who walks into it. A Watcher Bird patrols the area and looks for players, and the Blue Whale, the mod's one main boss, is reached through the same theme of internet horror legends. The boss has high health and strong attacks and can defeat an unprepared player quickly, so the fight calls for good equipment. Defeating it drops its own collectible note.
Crow feathers and other new crafting materials come from the biome and the creatures in it, feeding into equipment and items inspired by online horror. Installation runs on Fabric and Forge, and the mod is set up for client and server, so the server and every player need it. Files are published for 1.19.2, 1.19.4, 1.20.1 and 26.1.2, with 1.0.1 as the latest Fabric file for 26.1.2 and the latest Forge file for 1.19.4. The code is not open source; the mod is released under All rights reserved.
