Zombie marble quarry

The zombie marble quarry can be built in the cliffs north of the cabin in the woods. It's an extension of the marble quarry but the zombies don't need any wood wedges for their work.

After unlocking zombie quarrying II, you can build up to two mines: A left and a right variant.

Note: You don't have to build the player's marble quarry in the middle first.

Miners
To employ a zombie, walk next to the wooden stand and hit "E" to put it to work. If you want to stop the mine, grab the zombie out of the wooden stand by walking next to it and hit "E" again.

The marble blocks are stored on the stone stockpile near the cabin in the woods. Without this, it won't work. This sign on the blocks means, that the stockpile is full (or missing) and the work is blocked until some storage space is freed up (or constructed).
