Reason: please use the first argument of the template to provide a brief explanation. (Discuss in Talk:Urban Terror#)

"Urban Terror™ is a free multiplayer first person shooter, it can be described as a Hollywood tactical shooter; somewhat realism based, but the motto is "fun over realism". This results in a very unique, enjoyable and addictive game." [1]



There are several urbanterror packages in the AUR. If you want to do a full installation of the client, you will probably want this package.

Running Urban Terror in a second X server

You might want to run this game in an extra X server. To do that, create a new bash script with that content and mark it as executable:



xinit /usr/bin/urbanterror $* -- :1

Now you can use CTRL+ALT+F7 to get to your first X server with your normal desktop, and CTRL+ALT+F8 to go back to your game.

Because the second X server is only running the game and the first X server with all your programs is backgrounded, performance should increase. In addition, it is much more convenient to switch X servers while in game to access other resources, rather than having to exit the game completely or alt-tab out. Finally, it is useful if Urban Terror crashes. Simply CTRL+ALT+BACKSPACE on the second X server to kill that X and all processes on that desktop will terminate as well.


Prepare the game files

There are two ways, use the second one if you are low on disk space.

Extract your pk3s (recommended)

Note: This requires about 1GB of free space.

To get something to work with, you need to extract Urban Terror's pk3 files to a new folder:

install -d ~/urtmapping/q3ut4
cd ~/urtmapping/q3ut4

bsdtar -x -f /opt/urbanterror/q3ut4/zpak000_assets.pk3 --exclude maps
bsdtar -x -f /opt/urbanterror/q3ut4/zpak000.pk3

Give GTKRadiant write access to the game folder (needs much less disk space)

Note: Only recommended for single user machines.

GTKradiant creates a few own files inside game directory on creating a game profile. This means that you can own to the Urban Terror folder temporarily until these are created:

chown yourusername -R /opt/urbanterror

Then start GTKRadiant and configure the game profile. Close it afterwards and restrict access again with:

chown root -R /opt/urbanterror

Please note, that your user will own the newly created files until they get deleted (which is just what we want in this case).

Install a level editor

It might be possible to create Urban Terror maps with other level editors, such as netradiant for example. If you know how to do just that, please add it to the wiki.

ZeroRadiant (gtkradiant-svn)

Build and install both gtkradiant-svn and gtkradiant-gamepack-urt-svn from the AUR.

Start gtkradiant by either typing its name in a terminal or clicking the new menu entry. You will see a dialog, choose Urban Terror (standalone) in the drop-down list and Template:Filename as engine directory (not q3ut4). Click OK in the next window and the editor should pop up.

Here is a nice guide that explains how to create your first map as well as some Urban Terror specific things you need to watch out for.

Test your map

Copy your compiled .bsp mapfile to Template:Filename and run:

urbanterror +set fs_game iourtmap +set sv_pure 0 +map ut4_yourmap


Fix urbanterror_ui.shader

Open up Template:Filename in your favorite editor and delete lines 29-55 (from /* to */), because gtkradiant will not recognize this part as a comment and would try to parse it.

Problems with libcurl

UrbanTerror may complain that it cannot autodownload missing files because the cURL library could not be loaded, even though the cURL package is installed. UrbanTerror expects the shared library file to be called libcurl.so.3, but Arch Linux currently uses libcurl.so.4 .

To remedy this, start UrbanTerror, and from the main menu bring down the console with the grave key, tilda, or Shift-Esc. In the UrbanTerror console, type:

cl_curllib libcurl.so.4

Note that this is the UT console and not a terminal emulator. The changes should now be persistent and you should be able to download maps if the game server has their end configured correctly.
