The Doom Classic Unity port is a series of official ports of Doom and Doom II initially developed by Nerve Software in cooperation with id Software and first published by Bethesda on July 26, 2019 as part of the "Year of Doom" promotional campaign. It was initially announced on stage during the QuakeCon 2019 (DoomCon) keynote presentation. The port is based on the Doom Classic codebase, but replaces the id Tech 4 shell with one based on the Unity game engine. This offers immediate portability to a wide array of targets - the Doom and Doom II ports were available at launch for the Sony PlayStation 4, Nintendo Switch, Microsoft Xbox One, the Google Play app store for Android, and Apple's iOS app store.

Differences with Doom and Doom 2

Ultimate Doom and Doom II

Local multiplayer is available.
Cheat codes are available and accessible via the Options menu.
There is no confirmation when selecting Nightmare! skill.
On Nightmare!, the fast monsters mechanic has been removed entirely: fireballs shot by imps, cacodemons, barons of Hell and Hell knights are no longer sped up, and neither is the running speed of demons. Monsters retain increased reaction times.
The pickup sprites for the stimpack, medikit, and berserk (STIMA0, MEDIA0, PSTRA0) are modified in compliance with the Red Cross' wish that its symbol not be used in games. Instead, the symbol is replaced by a red and white pill.
The DMENUPIC that was the title screen in the original Xbox 360 version is used here.
Unlike the Gravis UltraSound Classic patch set v4.11 used by the BFG Edition, the music originally played at a noticeable reduced rate and wrong sound samples. This was later rectified with the September 27, 2019 update where the music played now closely resembles if not similar to the Roland SC-55 sound font.

Ultimate Doom specific

All animation from the intermission screens has been restored; they were originally missing from the BFG Edition.
The NIN logo on E4M1: Hell Beneath has been removed.

Doom II specific

All Wolfenstein SS have been search-and-replaced by zombiemen.
No Rest For The Living is excised from tnis port. In its place is the inclusion of The Master Levels.
BFG Edition's MAP31: IDKFA and MAP32: Keen has been reverted back to MAP31: Wolfenstein and MAP32: Grosse alongside their respective map music, D_EVIL and D_ULTIMA.
Map06: The Crusher has been edited to remove the linedef actions on the door track of the red key door which would crash the game.

Trivia

Doom and Doom II originally shipped with much criticized Bethesda.net login screen upon startup (for the purposes of rewards via Slayer's Club), which in a later update made them less intrusive.
