I have finished the first of my homemade missions for Dust Tactics. These missions are stories more than balanced games and they work best if you play them once as the attacker and once as the defender to see who does best.
This first mission is a two part story where Allied troops infiltrate an Axis research lab in Finland (I'm staying away from Antarcica as the official missions set the story for that theatre of war).
Below is the first mission map and all the missions details can be found in the PDF that you can get here: www.at43-confrontation.co.uk/dust/scientists.pdf

Missions 2 map:

The first mission uses 22 wall sections so you need a way to have 4 extra walls.
You will also need 8 models that can represent scientists. In the first mission these don't do anything but in the second mission they move around as a unit and for that reason I made a card to use in the game:

As you can see the scientist unit has one wound for every model in the unit and the PDF explains that you can group scientists into units of various sizes depending on the number of scientists you captured in the first mission.
