I was referring to the N64 and the absence of a specific "N64 counterpart" for those maps.
Yes, and to which I said:
Interesting, 'cause every time I enter either of those maps, their corresponding track is always in the background...
Subterranean Caverns and Egyptian Temple always play their corresponding single player mission track in the background every time those two stages are played in.
In fact, this applies to Facility, Bunker, and Archives as well.
I know that Temple, Complex, Caves, Library, Stacks, and Basement cycle through various tracks.
For the record, not knocking anyone's work. The N64 tracks for those two maps just have a different feel that I like.
