Ioquake3

ioquake3 is an open-source, community-maintained engine port of Quake III Arena, compatible with the original game data.

Client setup

⚠︎

Warning: The ioquake3 module is not yet upstream and will be available in the upcoming NixOS 26.11 release.

The game can be installed and configured using the dedicated programs.ioquake3 option.

programs.ioquake3 = {
  enable = true;
  settings = {
    name = "onny";
    com_maxfps = 125;
    cg_frawFPS = true;
    cg_fov = 115;
    r_mode = "-1";
    r_customheight = 1080;
    r_customwidth = 1920;
    model = "sarge/default";
  };
};

ioquake3 will use the demo game files. If you have purchased the game and have a full copy, you can point programs.ioquake3.baseq3 to the baseq3 file system path.

Dedicated server setup

⚠︎

Warning: Parts of this module are not yet upstream and will be available in the upcoming NixOS 26.11 release.

Following snippet will enable a Quake 3 Arena dedicated server. The map q3dm7 will be loaded.

services.quake3-server = {
  enable = true;
  openFirewall = true;
  settings = {
    rconPassword = "super_secret";
    sv_hostname = "My NixOS Quake 3 Arena Dedicated Server";
  };
  # Configure map rotation
  extraConfig = ''
    set d1 "map q3dm7 ; set nextmap vstr d2"
    set d2 "map q3dm1 ; set nextmap vstr d1"
    vstr d1
  '';
};

The server will use the demo game files, so various maps and assets won't be available.

If you have purchased the game and have a full copy, you can point services.quake3-server.baseq3 to the baseq3 file system path. Setting it, for example, to /var/lib/quake3, the game file is to be expected at /var/lib/quake3/.q3a/baseq3/pak0.pk3.
