The hills are made of some old chunks of plaster that I got from a friend ages ago, most of the roads have some filler brushed onto them to give a feeling of wear. The factory probably need a bit of tidying up, and I forgot to paint the helipad next to the army base, you can see the circle in the first picture.
Every tile is 20x20 cm. Anyhow, here it is:
Some scotia or skytrex vehicles to show the witdh of the streets.
