Hi Takyon,
Thanks for taking the time to reach out to us and for offering up the services that you mention!
However, based on the fact that the music in the game spans more than a decade and has been made by at least 4 main composers using various DAWs we simply do not have the project files that would be needed to attempt a re-master of the score.
I actually put the Full OST together for 5.0 last year and spent some time sourcing the best available quality versions of the pre-5.0 tracks and had to stick with previously released MP3s and WAVs as the producers simply do not have the project files anymore.
Thanks for reaching out to the team and for sharing one of your tracks too, I actually started out with Fruity Loops back in 2003 before moving onto Propellerhead Reason in 2004.
After having a chat with the other two composers currently on the team we have agreed that due to our various styles and musical backgrounds we are quite comfortable with the way we currently mix and master our tracks independently, but again thanks for offering your time and service!
