Ok, so this might seem like a pretty useless feature, but it’s just an idea.
Bone walls would be a direct upgrade to Wood Walls, with having 200,000 health instead of 100,000, but still inferior to stone wall’s 300,000 health. It would be a good way to use all the bone you might not have a use for.
I agree, there is onky so many axes and picks you can make and still have bone left. Good feature to upgrade our bases and increase construction levels
