Navigating the sunken corridors of the RMS Titanic in Call of Duty: Black Ops 4 Zombies presents one of the most intricate challenges in the franchise. Completing the main quest on Voyage of Despair requires meticulous coordination, precise timing, and a clear understanding of the ship's complex layout. This guide breaks down the essential progression steps to help your squad solve every puzzle and survive the final encounter.

Activating the Sentinel Artifact and Pack-a-Punch

Your journey begins on the Forecastle, where you must fight your way to the opposite side of the vessel. Reaching the Poop Deck allows you to interact with the Sentinel Artifact, which unleashes energy across the entire ship. Activating this key item opens up blocked passages and grants access to four pedestals required to unlock the Pack-a-Punch machine.

Aligning the Ship Clocks and Dials

Once the Pack-a-Punch is active, six distinct clocks located throughout the ship will display altered times. Four of these clocks will show unique times paired with elemental symbols nearby. You must locate the corresponding steering dials on the Bridge, Engine Room, and Poop Deck to set the exact hours and minutes observed on the clock faces.

Completing the Elemental Catalyst Trials

After setting the dials, sparking electrical outlets will appear in four different locations. Squads must lure and eliminate an Elemental Catalyst zombie right next to its matching outlet to reveal a ritual symbol on the floor. Interacting with these symbols teleports players into locked combat trials, which must be cleared in a specific order to retrieve the real Sentinel Artifact.

Confronting the Eye of Odin in the Boss Fight

With the artifact secured, players must interact with planetary symbols around the ship and complete a solar system sequence. Triggering the final portal sends your team into a multi-phase battle against the Eye of Odin. Concentrating high-damage gunfire on the boss while interrupting its wipe mechanics will finally defeat the entity and trigger the main quest ending cutscene.
