Here is the nearly completed set up. The table is a printed mat originally designed for Frostgrave. I’ve decided that my implementation of the Tomorrow’s War scenario Lost & Found occurs in the snowy north of planet Guerzim. Buildings are Metcalf N scale. Trees from Aldi.
The fireteams are mounted on group bases. TW advises that this works well enough since groups move together anyway. This should speed up play as well.
I’m still not completely happy with the set up. It’s still a bit too open so I’ll need to get some more clutter happening. But overall, I think the general set up is similar to the book recommendation.
