GZDoom is the open source game engine for ID Software's older games like DOOM, DOOM2, HEXEN and HERETIC or it's own unique games.

Freedoom
The Freedoom project aims to provide all the content needed to form a complete, entirely free/libre game for the Doom engine.
It is designed to be compatible with most custom levels, music, graphics and other modifications (“mods”) made for the original Doom games by Doom fans and artists over the decades.
Where to buy official DOOM?
You will need DOOM + DOOM II
.
The games DOOM 3
and DOOM 64
are not needed but we list them here because it is sometimes cheaper to buy the whole bundle.

GZDoom Controls
Known Issues
- Multiple controllers for local multiplayer don't really work as there are bugs between GZDoom and Steam Input.
- You need to have set the primary controller as player one as all the other players input will cause the inputs to loop sometimes. For example if you are docking the Steam Deck and want to use an external controller, set that controller as player 1 via Steam Input and not the Steam Deck.
- Pressing "Save configuration" within the GZDOOM options menu and you have mods that adds extra controls will wipe those extra controls. It is better just to set the inputs without pressing save as they still will be saved.
Standard Controls
The controls are semi based on the inputs from Timesplitters: Future Perfect
for the Playstation 2.
The controls here are described as an Xbox Layout style controller.

Mod Controls - Extras
Optional extra binds that can come into play for certain Project Brutality
or Brutal Doom
based mods.
Action | Button | Comment |
---|---|---|
Quick Melee / Special Action | L1 |
|
Throw Grenade / Second Special Action | L2 |
Replaces Zoom (most DOOM mods use Secondary Fire for this anyhow) |
Dash | R3 |
Replaces Quick Turn |
The mod needs more inputs
Many mods have also more inputs then what is bind-able on a controller, L1
, L2
, Dpad - Up
, Dpad - Down
are mostly free for those types of actions.
Try to bind L1
, L2
to more action orientated things you need to use more often. While Dpad - Up
, Dpad - Down
for things you use less often like Extra Menus.
If it is a new movement type that can replace quick turn try to bind it on R3
and replace Quick Turn or either of the L1
or L2
.
You are also free to change any of the Default binds shipped by RetroDECK and if you mess something up you can always reset GZDoom via the Configurator.
