yeah i like this song enough that i also didnt see it on here (possibly didnt look hard enough) but here it is (oh and i kept Abandoned In Place as the control song)

Control: Abandoned In Place

Buildup and Assault: Last Legs

Stealth (or setup whatever): Particle Ghost

Also FYI you might need CustomOSTFixer for this to work as its a different format just so i could put more than one song intro in with the folder
