FUEL Modding Toolkit

• Fully compatible with FUEL: REFUELED, FUEL: RESHADED, and other legacy mods by default
• Lua scripting
• Callback hooks to game events
• Interface functions to peek and poke game data
• Works with Games for Windows Live, XLiveLess, and XLiveLessNess
• Discord Rich Presence
• Bug fixes and performance improvements
• Better error messages for shaders and crashes
• Cool "Blue FUEL" logo :)

FMTK is fully compatible with legally obtained retail and Steam release copies of FUEL. Pirated versions of the game are not explicitly compatible with FMTK although they may work.

1. Download the latest release from the releases page. This will be the asset with a name matching the pattern fmtk-*.zip.
2. Unzip the release into the root FUEL directory (the directory containing FUEL.exe)
3. Verify that FMTK.exe and FUEL.exe are in the same directory.
4. Run FMTK.exe.

In the event of a crash or other game state locking event, i.e. "Error: Shaders processing has failed." or "The Game Disc could not be read.", please check the fmtk.log file in the mods/fmtk directory. If you cannot resolve the reported error yourself then please open an issue or contact an FMTK developer directly.

FMTK mods are only loaded when the fmtk.exe "Blue FUEL" launcher is used to run the game. To run the game without mods enabled, simply launch it how you normally would without FMTK; uninstalling FMTK is unnecessary. You can uninstall FMTK and all FMTK mods at any time by deleting the mods directory.

Join the Zouna Underground Discord for general Asobo Studio modding, beyond and including FUEL. If you plan on joining to ask a specific question, please read the FMTK FAQ first to see if it has already been answered.

Documentation for users and mod developers is available on Read the Docs. Documentation for FMTK developers is available on the FMTK Wiki. Bad documentation is a bug! If a piece of documentation is incomplete/incorrect open an issue so it can be improved.

For an inexhaustive list of things you can help with check out the How To Help wiki entry.
