Prepare for the ultimate challenge on You Shall Not Pass, an experimental map designed to push your skills to the limit! The starting point is a tiny valley with limited space, yet it is abundant in resources. Your task? Ascend to the top plateau before you run out of space (and coal). Once at the top, you are rewarded with a flat area for building a vast factory so you can utilize all the resources available to you. Will your excavators win the race against time or will your factory spiral out of control as your resources sputter out? Only the captains with the most robust plans (and trousers) can conquer this island of pain. This map is for experts only.
