I had a quick scan through though I recall doing/seeing a similar teardown in the past.
You will be looking at a mixture of 2d and 3d, with both sorts being compressed and stuck in sub files.
Fortunately the likes of tinke and crystaltile2 will be able to cut through most of it as far as getting it out of the files. Once there the NSBMD files did not want to play quite so nicely with the existing tools, though I did get some nice wireframe images.
