ACTIVATE Dredge Controls
Check the Prepper’s Note in the metal box outside the cabin. Swim along the southern side of the dredger, through the open window, then north, east (right), and south (right again).
Head up some steps to an upper hull you can stand on. Climb the ladder, then go down the stairs to the sparking controls. Flip the lever.
ENTER the Bunker
The dredger grinds away a section of the island. Jump through the window by the lever, swimming west into an underwater cave under the island. Surface inside a small cave, climb out to the north, and work your way along a narrow tunnel. Dive into the continuation of the underwater tunnel, until you reach a shaft. Surface at the hatch at the top of it. You’re in the bunker! Slay a possible rattlesnake and gather rewards from the metal table, including the Tanami Bunker Key Card. Use this on the locked door, which leads to a safe, a note, and a second hatch up to the surface exit by the cabin.
