All dialogue is spoken through the Ghost's comms.
Variks, the Loyal's voice comes in through another channel, clear and completely free of interference.
The Guardian fights their way through the Grottos, where a large scale battle rages between Fallen Wolves and Hive. A Wolf Servitor is floating at the far end of the caves, guarded by several Stealth Vandals.
The Guardian wipes out the Fallen and destroys the Servitor.
The Guardian runs through the tunnels, heading to the Refinery.
The Guardian finds more groups of Fallen and Hive fighting each other. Now members of the House of Kings have joined the battle, putting aside their rivalry in the face of a common foe. The Guardian kills all enemies in their way before moving on, finding the second Servitor.
The Guardian locates and destroys the second Servitor. Petra's signal starts to clear as she can be heard.
The Guardian emerges into the Rocketyard and reaches an old abandoned building next door. Fallen are guarding the entrance.
The Guardian kills the enemies and charges forward into the King's Watch.
The Guardian fights their way through several groups of Fallen as they ascend the building. They eventually come across two King Barons and a Wolf Baron intently watching a holographic map of the Traveler and a battalion of Fallen surrounding them. Eventually, the Guardian kills them all.
