About this Modpack

I do not own any of the content that are in the modpack, All work, mods, resourcepacks & shaders go to the original authors.

This modpack is basically just another Backrooms mod with some added flare for Multiplayer usage and whatnots... it's not as grand as the other experiments

This modpack is mainly focused on exploring SpacePotatos BACKROOMs mod and is meant for pure exploration with friends, nothing is for story, gameplay, it's just for a horror themed day to explore the backrooms with some friends and try to escape!
