This mod adds Mechanism 8 as a heist track you can pick. The buildup and control part is a little bit wonky at the moment for some reason and cuts out occasionally. If anyone has any suggestions on how to fix it I'd greatly appreciate it. I'm still very new to modding.
However, the stealth part sounds great and has no issues. Also, I don't mean to brag or anything, but the assault section is amazing and loops ABSOLUTELY PERFECTLY, and everyone knows that's the most important part.
The track for those that want to hear the song first: https://www.youtube.com/watch?v=qR9kvbXt4tk (I made it a bit louder than this because it was a little too quiet in-game with all the gunfire going on)
To install, just drop it into your mod_overrides folder.
