Machine Tools

Machine Tools are three parts in Call of Duty: Black Ops III on the zombies map Zetsubou No Shima. The parts are required to drain a pool of water in order to access the Pack-a-Punch Machine. All the parts are acquired in rooms adjacent the bunker where it is located.

The parts are acquired as follows:
 * 1) The player needs to first turn on the power. A small pipe will spawn in the pool of water in the power room opposite where the switch part drops.
 * 2) A valve wheel will be located somewhere in the underwater tunnels near Mule Kick.
 * 3) The last part is found in the room with the cocooned zombies. The player must knife the cocoons, to which one of them will drop a pressure gauge.

The player will then be able to go back to the Pack-a-Punch chamber to fix the pumps which will drain the water around the machine, thus allowing usage.
