Well, lacoste gave you a lot of source already... You must know that online, we have several gametypes we call schemes. There are plenty of these, basically, they are different game settings and in many cases, these Schemes have special maps, designed for that particular scheme.
To download schemes, navigate here:
https://www.tus-wa.com/schemes/You can find a column next to the name of the schemes, which sometimes contain a tick. That means that the scheme is officially used in one of our leagues, depends on in which column the tick appears (Classic League, Free League). I strongly advice you to download those schemes, which contain a tick in one of the columns, since those are either more popular and better known or better classified related to the other schemes that were uploaded to the site. When you download the scheme (which is a .wsc file), you have to put it into the following folder INSIDE your Worms: Armageddon installation folder (I will give you the default now):
C:\Team17\Worms Armageddon\User\Schemes

When downloading a map (.BIT, .LEV or .PNG files), you have to put those in this directory:
C:\Team17\Worms Armageddon\User\SavedLevels
You are able to create subfolders inside these folders
if you have the latest
updateTo select a map, you have to right click the map preview image in the top right corner of the screen. You will see this screen without the numbers of course.

Here, you can see number 21. You click that and the maps stored in your SavedLevels folder will show up, there you can select them.
I think that's all for now, if you have any questions, just ask.
