Essential improvements[edit]

Patches[edit]

All patches for the retail versions of Doom II: Hell on Earth (as well as Doom and Final Doom) can be found here.

Disable vertical mouse movement (DOS)[edit]

Game forces vertical mouse movement (forward and backward movement via mouse).
Automating novert in DOSBox (Steam release)[4]
novert is a program that disables vertical mouse input.
  1. Download novert and extract novert.com in <path-to-game> alongside DOOM2.EXE.
  2. Edit doom2.conf and doom2m.conf with a text editor, and in the [Autoexec] section, add novert.com before the line calling the game's executable.
  3. Save the changes in the *.conf files and close.

Source ports[edit]

Since the release of the engine's source code, various source ports have been released. See the link above for details and recommendations.

Enhancement mods[edit]

DOS and all source ports[edit]

  • Minor Sprite Fixing Project - Corrects sprite offsets and other graphical errors. Compatible with both original DOS release and source ports.
  • Perkristian hi-res Doom sound pack - The hi-res sound pack contains remastered versions of the Doom sound effects which have been remade at higher sampling rates (Doom's original sound effects were sampled at 11025Hz, which is considered fairly low-quality nowadays).

ZDoom-based source ports[edit]

  • Master Levels Menu Interface - An in-game menu that serves to replace the old DOS program that would launch a chosen WAD of the Master Level for Doom II expansion. This mod allows you to play them in one sitting without restarting the game or loading each individual WAD file.
  • WadSmoosh - Combines all the official classic Doom IWADs (Doom, Doom II: Hell on Earth, Master Levels for Doom II, and Final Doom) the user can provide, as well as the No Rest for the Living WAD from Doom 3: BFG Edition and the SIGIL WAD released for Doom's 25th anniversary, into a single PK3 IWAD with each game selectable as episodes. The bonus secret levels from the Xbox port of Doom 3 can also be integrated.
  • Roland SC-55 music packs - Soundtrack for Doom II recorded on an authentic SC-55, the midi player for which the soundtrack was mixed on. Choose either OGG or FLAC; MP3 does not support proper looping.
  • Smooth Doom - Smooth Doom is a spriting project/general enhancement that adds newly drawn frames to all of DOOM's weapons and actors.

Any source port[edit]

  • Widescreen Status Bar - Designed for compatible source ports that support widescreen resolutions. In addition to removing the brick patterns that appear on the side of the bar when upscaling it, it also helps prevent graphical glitches that sometimes occurs from the upscaling process. Some source ports may require adjusting the status bar upscaling size manually in their respective options menu to retain the intended aspect-ratio.

    "(modern branch only) Fullscreen is now borderless window (which, technically, it always has been, anyhow). Removed hacks which changed the desktop resolution in order to simulate exclusive fullscreen because they were a constant stability concern."
