How to install UE4SS (Windows) - EscapeTheBackroomsModding/EscapeTheBackroomsModdingDocumentation GitHub Wiki

🎮 What is UE4SS

As described by their Github, its a "Lua scripting system platform, C++ Modding API, SDK generator, blueprint mod loader, live property editor and other dumping utilities for UE4/5 games." If this don't make sense, it allows modders to inject code into Unreal Engine 4 games like Escape the Backrooms and these make the mods you play!
