Monsters from the backrooms
by Jack_Pulya
Monsters from the backrooms adds hostile mobs modeled on the Backrooms, a horror setting from online fiction, and is built for Forge and NeoForge.
What it does
The mod adds a set of detailed monsters, each with its own sounds and animations, that spawn in the world. Seven monsters are planned in total, and new ones are expected in later updates. Creative players can also find the monsters under the Spawn Eggs tab, which lets them place them directly without waiting for natural spawns.
Each monster has its own stats. One has 30 health and deals 12 damage, another has 60 health and deals 100 damage, a third has 60 health and deals 20 damage, and a small one has 20 health and deals no damage. One monster works as a jumpscare trap. GeckoLib is required, because the animated models depend on it. Every player and the server need a copy of the mod. Builds cover 1.20.1 – 1.21.1 for Forge and NeoForge, under the MIT License, and the code is not open source.
