FUEL: REFUELED is an enhancement modification for the game FUEL. It brings many changes, fixes and improvements to the base game, as well as adding new features requested by the community. As of 2011 the mod now also supports the FUEL Demo.
Copy all files contained within either the sub-folder "FUEL" or "FUEL Demo" within the .zip archive into your FUEL/FUEL Demo directory, overwriting where necessary.
Click on JSGME.exe and you will be presented with a list of mods to install.
The main part of the mod is "Core - FUEL REFUELED V15.4", you will need to activate this in order to play. All other mod packages are optional.
FUEL REFUELED V15.4 uses a separate saved-game file to the default game - if you are migrating from V15.3 you will need to make a copy of your saved-game and rename it as FUEL_RE_SAVE.
