Modding

Few people know that when you create a map, you are actually creating a mod, albeit with slightly limited capabilities. I'll reveal a secret: a map with the .h5m extension is actually an archive that can be opened with any archiver, like WinRAR. And an example of a mod is a set of maps, as presented in the Legends of the Ancients campaign. For example, open lota-data.h5m with WinRAR and try to find the map file there. ;)
