This track is another .pdmod with script replacement (because fuck Overkill and how they made the default tracks loop) so bundle modder is a must.

Anyway, this mod replaces boring and quiet Freeze with Explain Music from anime Jormungand. I think the track's maybe a bit too chill, but good to calm down and fine-tune your beautiful guns.
