I'm working that out.
Missions for something like this can be pretty simple because all you really need to to as a designer is put the right pieces in place. And the units present will be the units declared to that area by the players. My basic thought would be that you would have a goal line one side needs to reach or an area that one side must force enemy platforms out of. As for starting positions, you'd probably have a wedge or band of possible spawn locations... such that they start within 15-30 minutes of detection of each other, can fight the battle out in 2-3 hours max, and maybe with enough randomness to prevent spawn-killing and/or undue advantage due to a drop/restart.
Right now I'm assuming both sides see the .mu in advance of the match--no secrets. If secrecy is needed, there would have to be a dedicated GM to handle that.
