Some campaign files are also available here:

These work well on the Steam version; by implementing the original UI, players can experience the classic campaigns within Forged Alliance.
Although I am aware that FAF already includes the original campaigns, my version restores the Supreme Commander (SC) style for briefings and the UI, and I have also added cinematic voiceovers in various languages.
You may also need the "FA Campaign Mod Enabler" and the "Jon Mod" (which fixes an issue where the "Crab" units fail to spawn during the fifth mission of the Forged Alliance campaign when mods are enabled).
I have personally completed the entire ported campaign with multiple mods active, and everything works without issues.

If you encounter any problems, please reach out to me via GitHub.
Feel free to use or adapt anything I’ve created.
Thank you all for your support of this game!

Addendum:
I’ve noticed that there are still many players—both in my own country and on Steam—who play Supreme Commander (SC). This player base is what motivated me to invest time in creating this content.
Another point is that FAF (Forged Alliance Forever) updates so frequently that some mods struggle to function properly.
Since the older versions of Forged Alliance are stable and unchanging, it’s much easier for me to handle maintenance and fixes.
