==history==
Doom II “Bethsoft” is the version that is available on the Bethesda
store with the name “DOOM II (ORIGINAL)”.  This is separate to the
Unity version that is also available on the Bethesda store.  It is
intended to be part of the vanilla Doom release, albeit with SS
soldiers replaced with zombiemen.
Bethesda also released the “Bethsoft” version with DOOM Eternal, which
can be found in your DOOMEternal/base/classicwads folder.

UPDATE: Feb 12, 2021: 
https://github.com/Doom-Utils/iwad-patches/commit/98a2912e87076c315c73739163596ba7bfbbc142

- Add PlayStation Network Europe versions of TNT/Plutonia
- Renames old files from “psn” to “psn_usa”, homogenize doom2 also with
this change, since psn_eur likely predates the release on the Bethesda
Softworks store.


==history==
PlayStation Network versions for the PlayStation 3 (and later?)
consoles have two known versions of the IWADs depending on region: USA
and Europe.  The PSN Europe release has also been used for two
separate PC releases of the “vanilla” game: in the Bethesda Store as
“DOOM II (ORIGINAL)” and as part of Doom Eternal.
