Warzone 2100

Homepage of the Warzone 2100 Project


Warzone 2100, released in 1999 and developed by Pumpkin Studios, was a ground-breaking and innovative 3D real-time strategy game.

In 2004 Eidos, in collaboration with Pumpkin Studios, decided to release the source for the game under the terms of the GNU GPL, including everything but the music and in-game video sequences, which were released later.

State of the game

After the liberation of the Warzone 2100 source-code on December 6th, 2004, all proprietary technologies have been replaced with open-source counterparts.

Right now supported platforms are Linux, Windows, and macOS. There are reports that Warzone 2100 is working on BSD, too.

Development builds are a snapshot of the current state of development, from the latest (successfully-built) commit. Help testing these builds is always welcomed, but they should be considered a work-in-progress.

Reporting bugs

This game still has bugs and if you run into one, please use the GitHub bugtracker ( to report this bug. In order to faster fix those bugs we require that you follow these rules:

  1. If the game crashes you may save a memory dump. Please do so and upload it when reporting the bug. (Linux locates that file at /tmp/warzone2100.gdmp, Windows at /Program Files/Warzone 2100/warzone2100.RPT, macOS by clicking "Details" in the crash error message) A self created backtrace is just as useful.
  2. Give as much information about what you were doing before the crash/bug occurred.
  3. Try to reproduce the bug and add a description of the process to your bug- report.
  4. You may even upload save-games. These consist of one or two file(s) and one folder. All two/three are named after your save-game (e.g., MySaveGame.gam and the folder MySaveGame).
  5. Bug-reports are not submit-and-forget. It may be that you forgot some information or forgot to upload a file. So it is, too, in your interest to watch the bug-report after it has been submitted. Additionally you receive e-mails of comments to your bug-report.


Warzone 2100 uses an own sub-directory in a user's home directory to save configuration data, save-games and certain other things. Additionally you can use this directory to place custom maps and mods so the game can find them. The location of this directory depends on the operating system.

Warzone directory under GNU/Linux

Under GNU/Linux, Warzone conforms to the XDG base directory spec.

By default, the directory warzone2100-<version> can be found in your home-directory under the path ~/.local/share/. (If the XDG_DATA_HOME environment variable is defined, the Warzone folder will be located within $XDG_DATA_HOME.)

The leading dot in the .local part of the path indicates that it is a hidden directory, so depending on your configuration you may not be able to see it. However, you can still access it by typing the path into your address-bar.

Warzone directory under Windows

The directory Warzone 2100 Project\Warzone 2100 <version> is located under the %APPDATA% folder.

Typical %APPDATA% paths:

  • Windows XP: \Documents and Settings\$USER$\Application Data
  • Windows Vista+: \Users\$USER$\AppData\Roaming

Hence, the default path for the Warzone configuration data on Windows Vista+ would be: C:\Users\$USER$\AppData\Roaming\Warzone 2100 Project\Warzone 2100 <version>\

By default, the %APPDATA% folder is hidden. Entering: %APPDATA%\Warzone 2100 Project\ into the address bar of Windows Explorer will browse to your Warzone directory.

Warzone directory under macOS

The directory Warzone 2100 <version> can be found in your home-directory at: ~/Library/Application Support/

By default, recent version of macOS hide your account's Library folder. To view it in Finder, hold down the Option (⌥) key while clicking the Go menu, and your Library folder will appear as a menu choice.

Configuration file

The configuration file is just called 'config' and contains several configuration options, some of them can be changed by using command-line options or using the in-game menus, others can only be changed by editing the file by hand.

If at any point you did something wrong, you can delete the old configuration file and just restart Warzone 2100. Then the game will regenerate a new configuration file with default values.

Command-line options

Warzone 2100 can be started with different options and arguments. For a list of these options, run the game with the --help option.

Notes: These options all have two dashes (--), not one dash only (-). Also, if the option has an argument, you need to separate the option and its argument with a '=' sign - spaces do not work.

Note: Some options have corresponding entries in the configuration-file and will persist from one start of Warzone 2100 to the next.

Multiplaying via internet

There are two methods to start a multiplayer-game via internet: using the host's IP or using the lobby-server. Make sure to be able to communicate on TCP-ports 2100 and 9999. Note that for port forwarding, you only need to configure your router to forward port 2100.

You can choose whether to connect via Lobby or IP:

  • If you choose IP, Warzone 2100 asks you for the ip-address of the host and will try to connect to that IP.
  • If you choose Lobby, Warzone 2100 will connect to the lobby server, as long as the lobby-server-address in your config-file has not been changed.

You will see a list of games from which you can select one.

You can kick unwanted players out of not-yet-started game by clicking left on them while holding the right mouse button.

When you are hosting a game it will automatically be listed on the lobby-server. If you do not want your games to be listed on the lobby-server, you have to change the entry "" in your config to some- thing invalid as "nomasterserverplease".

If you then want to see the games that are listed on the lobby-server you may enter "" when prompted to enter the host's IP or change the entry in the config-file back. You will have to restart Warzone 2100 in order for config-changes to take effect.


Like many other games Warzone 2100 features a certain set of cheats that can be used to have an advantage in the singleplayer-campaign and skirmish-games, or to just help mod- and map-makers with testing. Cheats do not work in multiplayer, unless all players agree to it.

Cheats are likely to contain or trigger bugs, so use with care, especially during campaign.

Entering cheat mode

To be able cheats while in-game, press shift and backspace simultaneously. An on-screen message should appear telling you that cheat-mode has been enabled. You can disable it using the same key combination again.

Pressing ctrl+o opens up the debug menu, which is useful for inspecting the game state, or just messing around.

Cheat commands

After activating cheat-mode cheats can be entered using the normal chat- function. Cheats are ordered by their use and where they can be used.

There are many cheat commands. Some examples:

  • "biffer baker" - Your units do more damage and are stronger
  • "double up" - Your units are twice as strong
  • "give all" - Allows you to build and research everything
  • "work harder" - All currently active research topics are instantly researched
  • "research all" - Everything is researched instantly
  • "let me win" - You win the current campaign mission
  • "superpower" - Gives you maximum power

Modding information

Warzone AI, maps and campaign can be scripted using javascript.

How to build

Getting the Source

To properly build the game, either:

  • Download a release tar.xz, which contains all the source code and revision information.


  • Clone the Git repo:

    git clone
    cd warzone2100
    git fetch --tags
    git submodule update --init --recursive

    Note: Initializing submodules is required.

Do not use GitHub's "Download Zip" option, as it does not contain submodules or the Git-based autorevision information.


  • Prerequisites
  • Installing prerequisites:
    • Ubuntu 18.04+:
    sudo apt-get -u update
    sudo apt-get -y install git gcc g++ clang cmake libc-dev dpkg-dev ninja-build zip unzip pkg-config gettext asciidoctor
    sudo apt-get -y install libpng-dev libsdl2-dev libopenal-dev libphysfs-dev libvorbis-dev libtheora-dev libxrandr-dev qtscript5-dev qt5-default libfribidi-dev libfreetype6-dev libharfbuzz-dev libfontconfig1-dev libcurl4-gnutls-dev gnutls-dev libsodium-dev libsqlite3-dev
    • Fedora:
    sudo dnf -y update && dnf clean all
    sudo dnf -y install git gcc gcc-c++ cmake ninja-build p7zip gettext rubygem-asciidoctor
    sudo dnf -y install qt5-qtbase-devel qt5-qtscript-devel libpng-devel SDL2-devel openal-soft-devel physfs-devel libogg-devel libvorbis-devel libtheora-devel freetype-devel harfbuzz-devel libcurl-devel openssl-devel libsodium-devel sqlite-devel
  • Building from the command-line:
    1. Starting from the parent directory of the warzone2100 source code (which is assumed to be in a folder named warzone2100), create a sibling build directory:
      mkdir build
    2. Change directory into the sibling build directory:
      cd build
    3. Run CMake configure to generate the build files:
      cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX:PATH=~/wz/install -GNinja ../warzone2100
    4. Run CMake build:
      cmake --build . --target install

Windows using MSVC

  • Prerequisites
    • Visual Studio 2017 (Visual Studio 2015 may work, but 2017 is strongly encouraged)
      • If you do not already have Visual Studio installed, you can download the free Visual Studio Community from:
      • IMPORTANT: You need the fully-featured Visual Studio IDE. “Visual Studio Code” does not include the necessary support for building C++ Windows apps.
    • CMake 3.10+ (
    • Qt 5.9.1+ (
      • Here's a direct link to the Qt 5.9.9 installer.
      • You will probably need to register for a Qt account during the installation, along with activating your email.
      • Required components to install: MSVC 2015, Qt Script (even though it's labelled as deprecated). The MSVC 2015 components will work on MSVC 2017 / 2019, and 32-bit versions work on 64-bit platforms.
    • Git (if not building from a release source archive)
    • 7-Zip (
    • Vulkan SDK (
      • Required only if you want to build with Vulkan support.
  • Preparing to build: Build dependencies are provided via vcpkg from Microsoft.
    • Run the get-dependencies_win.ps1 script from powershell in order to download and build the dependencies.
  • Building from the command-line:
    • Change directory to the warzone2100 repo directory
    • Configure
      • Visual Studio 2017: cmake -H. -DCMAKE_TOOLCHAIN_FILE=vcpkg\scripts\buildsystems\vcpkg.cmake -Bbuild -G "Visual Studio 15 2017"
      • Visual Studio 2015: cmake -H. -DCMAKE_TOOLCHAIN_FILE=vcpkg\scripts\buildsystems\vcpkg.cmake -Bbuild -G "Visual Studio 14 2015"
    • Build
      • Release: cmake --build build --config Release
      • Debug: cmake --build build --config Debug
  • Building using Visual Studio 2017:
    1. Open Visual Studio 2017
    2. Open the warzone2100 folder using File > Open > Folder...
      • Allow Visual Studio some time to load the project and retrieve information from CMake.
    3. Create a VS CMake settings JSON file using CMake > Change CMake settings. You can also reach this dialog by clicking "Manage Configurations" in the configuration dropdown in the toolbar. Make sure the CMake components in Visual Studio are installed (by running the Visual Studio Installer).
      • This creates CMakeSettings.json
    4. Add the following variables to CMakeSettings.json:
      • To cmakeCommandArgs, add: -DCMAKE_TOOLCHAIN_FILE=vcpkg\scripts\buildsystems\vcpkg.cmake -DCMAKE_PREFIX_PATH=C:\Qt\Qt5.9.9\5.9.9\msvc2015 (check your Qt installation path)
      • If you're running a 64-bit platform, you need to set the compilation to 32-bit by setting inheritEnvironments to [ "msvc_x86_x64" ]
      • Note: Visual Studio automatically escapes and turns each \ into \\
    5. After letting Visual Studio re-run CMake configure with the new settings, you can build using the CMake menu.
