Replaces the in-game Diamond Heist (PD:TH)assault music to sound more like the soundtrack version of Breach of Security. Most likely won't work with other soundtrack audio mods, due to this one editing the music.bnk file.
If you want a preview, just listen to the song Breach of Security from the PD:TH Soundtrack. The original sounds like from around 1:00 to 2:00, whereas this version is from 1:00 to the end.
