Steam is input to the bottom face of the block. Items can be input by any face.
It has two GUI slots, and an internal storage of 10,000 steam. The middle slot is used for ammunition, and the bottom right corner slot is for upgrades.
If an upgrade has been installed in the Turret, its consumption and the time between fires is dependent on that upgrade. By default, it will fire every 100 ticks and consume 100 steam per fire.
It cannot currently be crafted.
