DERP v0.7.2
Pre-release
What's new in v0.7.2
Invert mouse look. A new F4 option under Display → View, shown while
Mouse look is on: pushing the mouse forward tilts the view down, like a
flight stick. Off by default. It works in DOOM and Heretic and is saved
with the other graphics settings.
DERP, the DOOM Engine Remaster Project. Each download includes Freedoom, so you can
play straight away; add your own WADs to play DOOM, DOOM II, Heretic or custom maps.
Download
| System | File | How to play |
|---|---|---|
| macOS 11 or newer (Apple Silicon and Intel) | DERP-mac.zip |
Unzip and open Play DOOM.app. Choose your WAD folder or click Play Freedoom. |
| Windows 10/11, 64-bit | DERP-windows.zip |
Unzip, drop your .wad files into the wads folder and run doom.exe. |
| Linux, x86-64 | DERP-linux.tar.gz |
Unpack, drop your .wad files into wads and run ./doom. |
DERP-source.tar.gz is the complete source of these downloads: the
game's code plus the exact SDL and Nuked OPL3 sources it is built with, so it
builds without an internet connection. GitHub's "Source code" archives hold
the game's code only.
With no WADs in the wads folder, Freedoom starts. With a base game (such as
doom.wad or doom2.wad) and a custom map WAD, the map is loaded on top of the
game. Controls and options are in PLAY.md.
macOS: the app is not notarized by Apple, so the first launch is blocked
with "Apple could not verify…". Click Done, open System Settings → Privacy &
Security, scroll down and click Open Anyway next to the message about
Play DOOM, then confirm. After that it opens normally. (Alternatively, run
xattr -dr com.apple.quarantine "Play DOOM.app" in Terminal.)
Windows: the program is not code-signed, so SmartScreen may say "Windows
protected your PC". Click More info, then Run anyway.
Linux: you need a Vulkan driver for the 3D renderer; without one the game
falls back to the classic renderer.
Before you play
This is a pre-release. The Mac version is the most tested. The Windows and Linux
versions are built automatically but have had little real play, so please
report problems.
Supported maps: vanilla and limit-removing, including DEHACKED patches. Boom,
MBF21 and GZDoom maps are not supported. Heretic plays from your own heretic.wad
or HERETIC.WAD; Hexen is not supported yet. Multiplayer is not implemented.
