UPBGE, or Uchronia Project Blender Game Engine, is a free and open source 3D game engine for Linux, Windows, and MacOS. It is a fork of the old Blender Game Engine, allowing users to develop games entirely within Blender. Compared to Blender, UPBGE features cleaner and improved Game Engine (BGE) code, introduces new experimental features, and removes outdated features from Blender. It also incorporates official Blender patches into its codebase to ensure compatibility with the latest Blender application.
