From the campaign:
We have just unlocked our first Add-on Stretch Goal at £75K, and it's a winner…
The Mines of Minerva are available to add to your pledge right now. We have made two add-ons for this and you can choose whichever suits you best.
This set gives you all the Mine components as per the Stretch Goal image. A great add-on that adds a whole new themed area to your terrain and really brings new flexibility to scenarios.
