I don't really see why you would add a map that's supposed to be part of a campaign separately unless it is that different from the rest of them and would work as a standalone. There is the Map Development forum for incomplete works if you seek attention and feedback.

Also, delve into the map rules:
Map Submission Rules

You need to provide a more detailed description for your map. Please check Map submission rules for more information.

Well, as interesting as this might want to be... the camera movements make me dizzy.
I suggest replacing the movement arrow keys with WASD.
This map is not finished. There are character classes not yet implemented.
There's a free slot in the lobby right before starting the map. You might want to fix player/forces settings.

To me, it's quite unplayable. Of course, I never liked these types of games in the first place, games like the Might & Magic series, I mean.
