"I have a gun and I refuse to walk to search for ore patches."
If you belong into this category, and for the sheer fun also have installed the Big Bertha mod ("Bigger artillery") for an increased range of delivering goods to customers, then this mod is for you.
All it does is to add a new artillery shell which doesn't cause a lot of damage but damages a large area - and reveals the content of the map.
So if you ever thought: "what's over there in the uncharted area?" - either walk or send a shell to take a look.
Gallery explanation:
The gallery shows the difference between regular artillery shells (area of effect size: 7) vs the knock knock ari shell (area: 300). The two screen shots with the map view are taken ingame, and each city block of the railway system cover 4x4 chunks. The affected area can be changed in the configuration.
