How do I install a Map?

To install a map, move the downloaded .wz file to the "maps" folder in your config folder...

Windows

XP or lower

C:\Documents and Settings\<username>\My Documents\Warzone 2100 <version>\maps

Vista or higher

C:\Users\<username>\Documents\Warzone 2100 <version>\maps

Mac OS X

/Users/<username>/Library/Application Support/Warzone 2100 <version>/maps

Linux

/home/<username>/.warzone2100-<version>/maps

If the "maps" folder doesn't exist, create it.

Maps must be in ".wz" format, (Warzone Zip). If you have some other format, see the "Map Format" panel below.

<username> is your login name

<version> is the game version, eg. 3.1

Map Format

If you downloaded a map and ended up with a ".zip" file, follow these steps to fix that:

Upgrade Internet Explorer to at least version 9 or above, or use a proper web browser like Google Chrome.
Then try downloading the map again. You should get a ".wz" file not a ".zip" file.

Note that ".wdg" files are an old map format that's not compatible with recent versions of Warzone. If you have one:

Try and find a newer version of the map by searching in Addons or Forums tabs on the Warzone website.
Or, convert the map manually as described on the old developer wiki.
