BiggerBackrooms

Description

This mod increases the lobby player limit from 4 to 16, allowing you to host larger sessions in Escape the Backrooms. It's a Lua LogicMod that runs via UE4SS. The host also gets extra tools to manage the lobby and keep players moving once inside a level.

Installation instructions

You need UE4SS for Escape the Backrooms installed and working first. Make sure BPModLoaderMod is enabled in your UE4SS setup.

Main Features

Lobby

• Max players slider: 1 to 16
• Lobby player list expanded to show more than 4 slots.
• Session / game mode max player values patched at runtime
  

Host tools (F5 menu or hotkeys)

• F5: Mod Menu — Shows Key Bindings Only
• F6 or 1: Teleport All to Host
• F7 or 2: Force Spawn Once (for when the game refuses to spawn additional players)
• F4 or 3: Toggle Player Collision On/Off
  

Player Collision

• Off by default in gameplay levels
• Host-only: Uses the game’s SetIsOverlapOnly so it replicates to other players without them needing the mod.
  

Debug (optional)

• F8: Manual Patch Complete
• F9: Log lobby/session info to UE4SS log
  

Requirements

• UE4SS-ETB (the ETB-specific build, not generic UE4SS)
• BPModLoaderMod enabled
• Host must have the mod installed for lobby limits, host tools, and no-collision to apply.
  

Clients can join a 16-player lobby without the mod, but only the host can use the menu/hotkeys and control collision.
More than 4 players is still experimental in this game. Crashes and weirdness can happen. That’s the game, not necessarily the mod.

Shout Outs

Thanks to Reokin for the original 16p Max Lobby mod. A lot of the ideas here (force spawn loop, player collision toggle, host tools) came from digging through that mod and trying to replicate the same features in pure Lua.
Thanks to the UE4SS and BPModLoader folks for making runtime modding possible without rebuilding the whole game.
