How would I create a plateau?

Hi guys.
Can someone point me in the direction of any information that would be useful in trying to achieve the following.

I want to create a multi square plateau. In that when atop the plateau a unit will receive no terrain combat modifiers when fighting a neighboring unit on the same plateau. If a units are fighting up/down the plateau then regular hill combat modifiers would apply.

Any information is appreciated.

Apologies if I have posted in the wrong forum, I'm kind of new here.

Yes, it's the wrong section, questions belong to the main forum. A moderator will hopefully move this thread soon to there.

If i understand you right, then you want to add another terrain level to the game.
If it is that, what you want to do, then i have to disappoint you: It can't be done.
But you could look at the mod "Dune Wars", which has a good workaround for a new terrain level.

Oops, sorry..
I tried to edit and move it myself but I don't think the functionality exists.

Anyway I thought I would add some more information to clarify what I'm trying to achieve.

Here is a picture done in photoshop


You can see the Archers atop the plateau.
There would be no combat modifiers if they attacked a unit at position 2.
Regular hill combat modifiers would be used if a unit attacked them from position 3.

Looking into dune wars now.. thanks

The futuristic mod Planetfall has what you describe. Check the heightmap from the mod or contact the lead designer, Maniac.

Thanks..
Will check it out this weekend.
