1. Contents of Warzone 2100
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.
Additionally all multiplayer-maps that were available in Warzone 2100 1.10,
the last official version by Pumpkin Studios, are available in Warzone 2100 as
2. State of the game
After the liberation of the Warzone 2100 source-code on December 6th, 2004, all
proprietary technologies had been replaced with open-source-counterparts.
Right now supported platforms are GNU/Linux, Mac OS X 10.4-10.6 and Windows
(98 - 7). There are reports that Warzone 2100 is working on BSD, too.
2.1 Reporting Bugs
This game still has bugs and if you run into one, please use the 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, Mac OS X 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
3. Try to reproduce the bug and add a description of the process to your bug-
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.
3. Configuration
3.1 Warzone directory
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 the warzone-dir can be found in your home-directory, it's called
".warzone2100-<version>". The leading dot 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 is called "Warzone 2100 <version>" and is located in "My
Warzone directory under Mac OS X
The directory "Warzone 2100 <version>" can be found in your home-directory at:
~/Library/Application Support/
3.2 Configuration file
The configuration file is just called 'config' and contains several configura-
tion 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 may delete the old configuration
file and just restart Warzone 2100. Then the game will regenerate a new configu-
ration file with default values. It may be wise to not delete and instead backup
your old configuration file in case you want to keep other options.
The shown values are the default values.
Toggles permission to play with allies in Skirmish and multi player mode
on (1) and off (0).
Toggles subtitles during video sequences on (1) and off (0).

pink (6) and cyan (7).
ColouredCursor=0 on Windows/Linux, 1 on Mac OS X
Toggles whether to use hardware-accelerated black/white cursors (0) or
slower coloured cursors (1).
Toggles debug mode on (1) and off (0). --cheat sets this to 1. In order
to unset to 0 the file has be to edited by hand.
Sets the difficulty for campaign game: easy (0), medium (1) or hard (2).
This value is not changed by difficulty-cheats.
Sets whether to play FMVs fullscreen (0), 1x (1), 2x (2), or fullscreen
preserving aspect ratio (3).

Sets the volume for sound effects (user interface sounds and advisor)
ranging from 0 (no sound) to 100 (loudest).
gameName=My Game
Sets the game name for skirmish and multi player games; limited to 79
bytes, so beware when using multi-byte characters such as German umlaute
or Japanese kanji.
Sets the port Warzone 2100 will listen to when hosting games, so make
sure that you can communicate on that port.
Sets the gamma value Warzone 2100 will use. This will have an effect on
the whole screen, so do not be surprised to see your whole screen getting
brighter/darker when playing in windowed mode. Minimum value is 10 and
stands for 0.5 times the normal screen intensity, maximum value is 200
and stands for 10 times the normal screen intensity.
Sets the height of the resolution Warzone 2100 will use; equivalent to
the height value of --resolution.

Sets five predefinable messages used for multi player mode to throw at
your opponent. Enter chat mode and then press F1 (phrase0) to F5
(phrase4) to send the corresponding phrase. It is not recommended to use
these as it may not always work as expected. These are limited to 79
bytes, so beware if you are using multi-byte characters such as German
umlaute or Japanese kanji.
Toggles playing of audio CDs on (1) and off (0).
Sets your name used in skirmish and multi player games. There is a
profile for every playername you ever played with in your warzone
Sets the default power level to use. You may choose any value between
-2147483648 and 2147483647 (both times inclusively) but Warzone 2100 will
recognise exactly three values only and fallback to medium power levels
(400), if you specify an unknown value. You can choose from low power
levels (100), medium power levels (400) and high power levels (700).
Whether to use left-click (0) or right-click (1) for ordering units to
move, attack, etc. Right-click ordering (1) makes the mouse buttons
resemble how they're used in most modern RTSes, such as the StarCraft
and WarCraft series.
Toggles friend-foe-colours on (1) and off (0). The value is not affected
by using Ctrl+Tab.
Sets the radar mode Warzone 2100 will use: Terrain only (0 or 1),

no heightmap (4). Any value greater than or equal to 5 will make the game
use terrain only mode.
Toggles the reopening of the build menu on (1) and off (0).
Defines the maximum scroll speed and scroll speed acceleration. Sane
values range from 200 (slow) to 4000 (fast). A value of 0 would stop

then. The built-in range of values in the options menu ranges from 100 to
Toggles the replay of video sequences on (1) and off (0). The default
value is likely to be changed in future releases as the videos have been
Toggles the rendering of shadows on (1) and off (0). Older graphics cards
may be unable to render the game at an acceptable speed while using
shadows. This value can be changed by --shadows (1) and --noshadows (0).
Toggles shaking of the camera when buildings are destroyed on (1) and off
(0). This option is not affected by the shakey-cheat.
Toggles the display of the frames per seconds on (1) and off (0).
Toggles sound on (1) and off (0).
Toggles the display of subtitles during videos on (1) and off (0). Note
that subtitles are shown even if the video does not exist.
Sets the texture size of terrain tiles in pixels. Valid values are 16,
32, 64 and 128. Using lower values can increase the game's performance.
Toggles the trapping of the cursor in the game window. Only useful when
playing in windowed mode. It prevents getting off the window and clicking
something behind it like another application or the desktop, so the game
itself loses the focus or becomes hidden behind another window.
Used for selecting a game-type, do not edit this.
Whether or not to enable (1) or disable (0) UPnP. When enabled, Warzone
will try to automatically configure port forwarding in your router, if
your router supports UPnP.
Toggles the effect used for unexplored terrain: Black tiles (1) or dimmed
tiles (0).
Sets the volume for voices (weapon sounds etc.) ranging from 0 (no sound)
to 100 (loudest).

WIDTH value of --resolution.
3.3 Command-line options
Additionally to the configuration-file Warzone 2100 can be started with dif-
ferent options and arguments.
Notes: These options all have two dashes (--), not one dash only (-). Trying to
use the options with one dash only will not work. The game will display a notice
when trying to use invalid command-line options. Arguments that need paths need
them in the form they are used on the operating system.
Starts the game in fullscreen-mode.
Starts the game in windowed mode.
--resolution WIDTHxHEIGHT
Sets the resolution Warzone 2100 will use; usable for fullscreen mode and
windowed mode.

--datadir path
Sets the data-directory to the path specified.
--configdir path
Sets the configuration-directory to the path specified.
--savegame name
Loads a saved game.
Enables the usage of cheats and debug-keys, see cheats and debug-keys.
Outputs a help message and exits; only useful when run from command-line.
--debug option
Shows debug information; option can be any of the following: all, main,
sound, video, wz, 3d, texture, net, memory, error, script. If you want
more than one option, you will have to use another --debug. The option
"all" contains every other option.
--debugfile file
Directs debug output to the specified file.
Outputs the Warzone 2100 version and exits.
--mod_ca mod-file
Enables the specified campaign mod. You have to specify the full name of

of the mod-file.
--mod mod-file
Enables the specified mod globally - for campaign and multiplayer. You
have to specify the full name of the mod-file. Global mods are only
useful when things are changed that affect both, campaign and multi-
Note: Some options have corresponding entries in the configuration-file and will
persist from one start of Warzone 2100 to the next. For example starting the
game with --nosound only once will silence it as long as you do not start it
with --sound or change the corresponding value in the configuration file. Fur-
ther information on command-line options can be found at the Wiki of the War-
zone 2100 Project (
3.4 Music
A playlist-system is used that can point to any *.ogg in your warzone music
path. However, if you just wish to play Warzone with your own music, it is far
easier to turn off Warzone music and use an external music player such as iTunes.
Warzone 2100 reads the playlist from the first location it is found, searching
in this order:
* Warzone-directory in your personal directory:
o for GNU/Linux: ~/.warzone2100/music/music.wpl
o for Windows: ~/My Documents/Warzone 2100/music/music.wpl
o for Mac OS X: ~/Library/Application Support/Warzone 2100/music/music.wpl
* Warzone-install-path:
o <whereverwarzoneisinstalled>/music/music.wpl
The playlist is just a list of songs you want to be played in-game, one song per
line. The only supported file format is Ogg Vorbis.
Note: Since we are using PhysFS we recommend you to use only Latin letters in
directory and file-names (more exactly this means: A to Z, a to z, 0 to 9, _-+
and space). You will receive the following error (running with --debug sound) if
"bad" characters are used: Failed opening [[PATH TO FILE]]: Insecure filename.
3.5 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.
4. Cheats
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-
mode (except skirmish).
4.1 Cheat-mode
To be able to use cheats in the first place, you will have to start Warzone 2100
with the option --cheat. While playing, press right shift and backspace simul-
taneously. An on-screen message should appear telling you that cheat-mode has
been enabled. You can disable it using the same key combination again. Enab-
ling/disabling cheat-mode is only possible while playing, not while in the
4.2 Cheats lists
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.
