About
Master Levels for DOOM II is an official expansion pack for DOOM II: Hell on Earth, released on CD in December 1995. It bundles 20 commissioned WAD map files built by outside level designers under contract to id Software, plus the separate Maximum Doom shovelware collection of thousands of community maps. id produced it to officially license and curate the wave of unauthorized commercial DOOM level disks that were appearing at the time.
The standalone product is no longer sold because the maps were folded into the later enhanced re-release of DOOM II, and the original Steam listing (appid 9160) was delisted.

⚙ Setup notes
DRM: Delisted Steam game (appid 9160) — these are the 1995 Master Levels WAD packs for DOOM II. Steam ships them inside a DOSBox wrapper (dosbox.exe runs doom2.exe + the master.wad maps).
Proton: ProtonDB rates it gold and the DOSBox wrapper runs fine under Proton/GE-Proton on the Deck.
Fix: RECOMMENDED — swap the slow DOSBox setup for a modern source port. Drop GZDoom into the install folder, rename gzdoom.exe to dosbox.exe so Steam launches it, place master.wad next to doom2.wad, and add -file master.wad to mount the maps.
Controller: The source port gives native controller support; for the vanilla DOSBox path apply a Steam Input keyboard/mouse layout.
Install: deckport only configures the prefix; it never bundles or links the game files.
The one thing to know
Supply your own copy. deckport links nothing.
DRM: Delisted from Steam (appid 9160); these maps were later folded into the DOOM II enhanced re-release, so the standalone product is no longer sold.
Fix: ProtonDB gold — the DOSBox wrapper runs under Proton, but vanilla DOSBox is fiddly and keyboard-only. Strongly prefer the GZDoom source-port swap (rename gzdoom.exe to dosbox.exe, mount master.wad via -file master.wad) for proper Deck-native controller support.
Controller: The vanilla DOSBox path is playable with a Steam Input keyboard/mouse layout.
Multiplayer: Single-player only, no servers involved.

Get the artwork
deckport never hosts game images. Open this game on SteamGridDB, pick
the cover / hero / logo / icon you like, and drop them into the
game folder under .deckport-art/ before you push it to the
Deck. The importer files them under the right names automatically.
Run it on your Deck
Two files: the one-time importer (deckport.py) in your
Deck's home folder, and this game's install helper. Copy the game
into ~/Games and run the helper with Steam closed — it
writes the recipe (binary, launch options, Proton version)
and registers the shortcut with artwork.
