Just wondering if is there's a way to insert my mod in a HOTS campaign.

bump :okay:

Hey there!
Sorry for not responding earlier, but I guess you will need to be clearer on that.

Do you want to insert your own map into the HotS-Campaign? Like adding another mission?
As far as I can tell, this surely is somewhat possible, but it is not easily done.

I remember trying to edit the final mission in WoL.
I managed to get the map file, could load it in the editor and save it again, but no matter what, when trying to play the modified version in the campaign, it simply loaded the normal final mission; I could not edit any mission of the campaign and override it the file in the actual campaign folder (I think it is inside a .SC2Data or something).

My bet is, that battle.net tries to validate your campaign datas in order to secure that one can not edit them to be able to get the achievements easier.
But I can not tell you that for sure.

O.o Seems like Blizzard would deter this for the sake of achievements alone.
