COD BO3 Zetsubou No Shima Gas Mask

First part: Mask. Locations: After Lab “B” near 115 water. All three locations are in the same area.

Second Part: Air Hose. Locations: Propeller Trap Area. Same on the first part, all are in the same area and easy to find.

Third Part: Air Pump. Locations: Docks. In order to get it this location, you need to turn on those two temporary power on Lab “A” and “B”. For how to do that, here’s the link. Once you are in the bunker. Open the power room then, look on your left and it will have another door. That door goes to the dock. This location is much smaller than Propeller Trap Area so its more easier.
