Which files do I need?
Just one, most of the time: DUDE for your system. Everything else is for Quake 4 players or is an optional extra.
| I want to play... | Download |
|---|---|
| DOOM 3, Resurrection of Evil or The Lost Mission | DUDE for Windows or DUDE for Linux / SteamOS |
| Quake 4 | DUDE for your system + the Quake 4 add-on for your system |
| ...and I'd like extra shading detail | Add the matching baked shading pack (optional) |
"Windows" means 64-bit Windows 10 or 11. "Linux" means any 64-bit x86 Linux, including SteamOS on the Steam Deck. There is no macOS version at the moment.
DUDE 0.9.8
DUDE for Windows Required
dude-win64.zip - 85 MB - the program plus its menu and settings files
DUDE for Linux / SteamOS Required
dude-linux-x86_64.tar.gz - 75 MB - runs on Steam Deck too
Both include everything for DOOM 3, Resurrection of Evil and The Lost Mission. Next step: the install guide.
Quake 4 add-on
Only needed for Quake 4. It contains Quake 4's game code (how weapons, monsters and the story behave), which comes from Raven Software's Quake 4 SDK. That code has its own licence, separate from DUDE's: free, non-commercial use only. So it is a separate download, with the licence file inside. It contains no Quake 4 game data: you still need your own Quake 4.
Quake 4 add-on for Windows Quake 4
dude-q4-win64.zip - 28 MB - use with DUDE for Windows
Quake 4 add-on for Linux / SteamOS Quake 4
dude-q4-linux-x86_64.tar.gz - 24 MB - use with DUDE for Linux
The add-on must match your DUDE version: always download both from this page, and update both together. Setup: installing for Quake 4.
Optional: baked shading packs
These packs add ambient occlusion: the soft darkening where surfaces meet, in the folds of a monster's skin, the creases of a weapon, the gaps of machinery. Without it, characters and props can look a little flat and "pasted on". The shading is computed in advance ("baked") once for every model of the game, so it costs almost nothing while you play.
- Not required. DUDE runs fine without them; they are large, so they are a separate download.
- Used by the Low to Nightmare presets on OpenGL 3 and Vulkan. Not used by Potato (the original look) or by the Path Tracing setting, which computes this shading live.
- Download once: a pack is not tied to a DUDE version. It only changes when the baking itself improves, and keeps working when you update DUDE.
- You can switch it off any time: F10 > Baked Occlusion Maps.
Pack for DOOM 3 + Resurrection of Evil + The Lost Mission Optional
z_baked_ao.pk4 (version 1) - 187 MB - one file covers all three games
Pack for Quake 4 Optional
z_baked_ao.pk4 (version 1) - 260 MB
How to install a pack
No unzipping: the .pk4 file is used as it is. Just put it in the right folder inside your game folder.
- DOOM 3 pack: into the
basefolder (next topak000.pk4). It also serves Resurrection of Evil and The Lost Mission. - Quake 4 pack: into the
q4basefolder.
Both files have the same name, so keep them apart: don't save one over the other in your Downloads folder. Upgrading from DUDE 0.9.7 or older? Delete the old z_baked_ao_*.pk4 files (props, weapons, roe, lm) from your game folders; this single pack replaces them.
