Vanilla-Backrooms
TLDR: Vanilla-Backrooms is a server-side only Backrooms mod based on Polymer, made with info from the Backrooms Wiki.
Ever wanted to put your friends in the backrooms, but it would be way too suspicious to make them download a mod?
Well then this mod is the solution off your problem!
This mod, which only has to be installed on the server (wheter that is a dedicated server or a singleplayer word doesn't matter), will bring them to the backrooms without them having to download even a singular mod. They won't even know what happened when they suddenly clip out of reality!
