OFF: Definitive Edition
A downloadable mod
OFF (2025) Original Soundtrack Mod
When OFF (2025) was revealed, the question was asked:
Will the original soundtrack be available?
And to this, the fine people at Fangamer said:
No.
This mod intends to replace the remastered soundtrack with the original Alias Conrad Coldwood soundtrack.
What difference is there between this mod and the original soundtrack?
This mod aims to recreate the original soundtrack by utilizing the Flac format soundtrack previously published by Alias Conrad Coldwood. I manually cropped and clipped the higher quality soundtrack to match the original 1:1, giving this mod a higher quality version compared to how the original sounded while retaining the original loop points. Think of it as just an HD version of the original.

- Game: OFF (2025) by Mortis Ghost and Fangamer (Steam Page, will open in new tab)
Disclaimer: This mod is not endorsed or official in any way, this is only a fanmade addition to restore the original soundtrack. I do not claim any rights or original works that belong to Alias Conrad Coldwood, or any samples that they have used in the original soundtrack.

Hey creator, if you got the time by anychance if you could take a look into the Nintendo Switch version as well? I'd tried using the patch to see if it worked on there, it boots with it but problem is that it throws you into a infinite loading screen loop after the new game initialization.
likely i'm guessing it has something to do with the value and hash being very different from the PC version and/or the file structure directory inside the bundle being different as well in comparison.
i can look into it and get it working on there.
awesome! thank you very much
If you need a tester i'll be glad to help out if so
Small clarification: Fangamer didn't say "No," they had offered Conrad to join for the remake, but he'd have to write new songs and also enter the soundtrack into a content ID system, which he understandably didn't want to do since he's too busy to write new music and wants the soundtrack to be free-use... Not to mention the heavy sampling could've been an issue.
Edit: Misinterpreted the description originally, my bad, but I still think this is good to know for people who may not.
Thank you! This is perfect so far!
You're amazing! Thank you for making this.
WE ARE SO BACK!!
Great mod, though just for clarification it's not really needed to backup the music file. If one wants to restore the original, you can just verify integrity of installed files on Steam and it'll redownload the original asset files.
thank you for commenting, i had put to keep a backup as that is how i handled it in my dev env during testing, but i can include it in the install/uninstall section ^-^
ur a saint
Thank you
