xOBSE
What it is
xOBSE is a free, open-source community fork of the Oblivion Script Extender for The Elder Scrolls IV: Oblivion. It expands the game’s scripting capabilities for modders and supports plugin loading through injection. Releases and changelogs are available from its public GitHub repository, with xOBSE 22.13 listed as the latest release. Windows is supported, and Linux users can run it through Steam Proton by renaming obse_loader.exe to OblivionLauncher.exe and launching through Steam. The project supports Steam and GOG editions, with GOG preferred, while Direct2Drive is unsupported. English official patch v1.2.0.416 is identified as supported; localized versions with different executables or patches may not work. xOBSE does not modify executable files on disk. Existing mods and plugins are a compatibility focus, although beta releases can introduce errors. Mod Organizer 2 requires additional setup instructions.
