Ok first of all why are you here if you don't know what this is, touch grass.
So I was unable to find one guide that would walk me through the process of installing a NFS: Heat mod on Linux from start to finish without running into some issue without running into some issue or another, this is what worked for me, your mileage may vary, but even if you succeed I hope you learned something, got some inspiration to try something else, and keep trying, I wish you luck <3.
If you're still here I will assume you have no interest in touching grass and you want to read this full-of-nonsense guide on how to install UNITE on your Linux machine, where nothing is ever easy. Fear not, I gotcha.
