About This File
This is, from where they come from: These are WADs, that have been published on a BBS. In the package THENST.ZIP came the two WADs THENEST1.WAD (E1M1), timestamp: 10/04/94 MM/DD/YY and THENEST2.WAD (E1M2), that has timestamp 10/06/94 THENST.ZIP has the BBS file description: The first two maps of the episode The Nest, for DOOM.
There was also another version of THENEST1.WAD on that BBS as THENEST.WAD (E1M1) with the timestamp 09/25/94 in the zip THENEST2.ZIP. That zip has the BBS file description: Final version of the DOOM PWAD file TheNest.
I include that version, because i'm a completist. Decide on your own, what's the unknown authors intention.
The BBS file description has been discovered here: http://cd.textfiles.com/svgames9501/CDR17/FILES.BBS ... and the zips here: http://cd.textfiles.com/svgames9501/CDR17/THENEST2.ZIP http://cd.textfiles.com/svgames9501/CDR17/THENST.ZIP
