This is the 1996 CD "Pfhrenzy" found on the Macintosh Repository here.
There was some interest in this CD on the Marathon Discord server when I pointed out this CD. Not everyone wanted to bother with emulating Mac OS, but they still wanted to see the maps at least, which can be played with modern Aleph One. Thus, I emulated it myself, and transferred all the files off of the CD and zipped them up for people to look over on whatever OS they preferred.
For this reason, most of the files will look weird or not work at all on Windows or Linux, or perhaps even Mac. I have done nothing to the files themselves aside from put them through 7zip.
