If you cannot find DOOM2.wad anywhere in the archives of the internet, then you can always buy DOOM 2 again on Steam, GOG.com or the Microsoft Store - these versions of the game contain the file you'll need. Consider it part of the gameplay experience! If you own a copy of Doom 2 for MS-DOS, Windows, Mac OS, Sega Saturn, Game Boy Advance, Tapwave Zodiac, N-Gage, Android, iOS, Xbox, Xbox 360, Xbox One, Xbox Series S, Xbox Series X, Nintendo Switch, PlayStation, PlayStation 3, PlayStation 4 or PlayStation 5, then you legally have a license for the file 'doom2.wad' - but you'll need to find a copy of it yourself. I don't want to get sued - Bethesda has access to Robert Trump's $66.6 million legal team, and 3D: Doom Daddy Digital does not!
Legally, I am not allowed to give you that file. As such, a copy of the file 'DOOM2.wad' is required in order to play. THATCHER'S TECHBASE is a game mod that uses the classic video game DOOM 2 (1994) as a base. (PRBoom players please note - this wad is best enjoyed with PrBoom+ 2.6.1, as I've used a UMAPINFO lump to add some extra flavour to the game.) Tested on PRBoom*, DSDA-Doom, ZDoom and GZDoom.
THATCHER.wad is a Boom-compatible pwad for DOOM II, and you can download it here (v1.2).
