How do you link maps, like when you enter a region you go to another map? For example, in the Founding of Durotar, Rexxar enters a region then is teleported to a new map.
Only in 1 player campaigns sadly not for multiplayer. but if your making a 1 player campaign u could just open up one of the wc3 campaigns and look at it...
If you wanna do something like the Rexxar-RPG (being able to enter & leave a map several times), you'll need a hell more work, just open one of the Rexxar-Maps and you'll see what I mean.
