I've sorted out every single song element from the game and put them in their respective folders for you to use. They are also chronologically labeled for easier access, so for example, if you wanted to piece together the whole track as it might sound for "Armed To The Teeth" during the casing phase, buildup, and assault phase, you would put (in your audio editing program of choice; I use Audacity) Assault buildup 1, then 2, then 3, then 3.5 (the holder), then 4, then Assault Phase - and so on and so forth. This allows you to clip whatever you want, add whatever you want, or create whatever delay/rush you might wish to do. Screencap for relevance.
Although I must warn you - the size of this download is 2.28 GB UNCOMPRESSED - meaning that this is the true size of the soundtrack after extraction (for reasons which are beyond me) - so it may or may not take a while for you to download. This is also why there is no download link for this file here as the size limit is 500 MB.
Having said that, click me to proceed to the file download.
See you guys around :D
