This plays in the Stronghold level, in the second game of course.
Since I have a bunch of time this summer, I might create a checklist of all tracks from HM2 and if they are sequenced or not, and, well, sequence the unsequenced. I don't promise, but single handendly holding half of such a great soundtrack would be cool.
By the way, there was supposed to be an OST from MADNESS: Project Nexus 2, but the power died when I was finishing the sequence. Holy hell.
