(Theory) Beta Xen model in nettest build 1

[pmtk_milk]

This is just a theory, and I have no proof to confirm it other than a model and some concept art.
At some point, some Xen maps may have been built, but it was at a very early stage and probably not with the best gameplay. I think the Xen we have looks somewhat unfinished, so to speak, because it was redesigned at the last minute, just a few months or weeks before the game's release. With this post, I'm referring to a possible Xen beta because I saw a video by XDehmian showing models found in Nettest 1, and it showed a kind of Xen machine, which immediately reminded me of some concept art depicting the same machine or being.

Xen maps were infact built, Alpha 0.61 document has like 15 Xen maps, and we have screenshot of presumably Gonarch's Lair in early development.
It wasn't really redesigned at last minute, different people had different vision of Xen maps. Brett Johnson made most ((if not all)) Xen maps, and as he himself said -- he had barely any support for Xen, people didnt cared for it until it was too late and it was time to wrap it all up.

Pretty sure Gonarch's Lair was by Dario. Additionally, there are changes done to Xen as parts of the original Nihilanth's Lair are now apart of C4A1 when they cut the original version for the final one. 0.61's map listing is also likely for the E3 1998 build, the descriptions below are for the 0.61 build along with leftovers from the 0.52 documents. If I had to guess, Xen started development when the team was concerned that Sierra would not give another extension for development time. So, circa Q1 1998.

And to OP, breather.mdl is not unique to Net Test 1, it is in the final game's files.
