About this project
What does Monsters from the backrooms add?
The "Monsters from the Backrooms" mod adds highly detailed monsters from the Backrooms. There are 7 monsters in total, but I plan to add more in the future. Each monster features unique sounds and animations to enhance the gameplay experience!
Note: Monsters do not spawn in the world; they are available only in Creative Mode under the "Spawn Eggs" tab.

P.S. Version 1.0.0 was hidden due to a fatal error that broke the game. Version 1.0.1 was hidden because it became obsolete; the minimum mod version for Minecraft 1.20.1 (Forge) is now 1.1.0, while for future versions (starting with 1.20.6 NeoForge), it will be 1.0.0 .
