Beginning in the City, the Guardian must make their way through the City alongside others, starting at ground level through Cabal barriers that are slowly taken down and up high across rooftops and platforms. Eventually, the Guardian rendezvous with the Vanguard and Suraya Hawthorne. Cayde-6 then opens the Vex teleporter for the Guardian to get to Ghaul's command ship.
From the Cargo Bay, the Guardian has to fight their way to an elevator to the upper, outside deck.
After beating this mission, the Guardian will need to go to the Tower and speak to Zavala. If he hasn't already, he will give the player an emblem and they will get to level 20 and complete the quest line.
