Walkthrough
- In the first chamber, Aquaman would first attack you but after you take off some of his health he'd realize you're allies and stop fighting. You must unite against many Starro-controlled Atlanteans.
- In the second chamber it is discovered the research station has found quicklime a potential weapon against the starros, but they were overrun. Aquaman demands to know why he wasn't informed, but a report in the first chamber indicate the Atlanteans in the station are loyal to a "true king" with a bid for the throne.
- The third chamber is found to be a hatchery; Aquaman attempts to stop them but was overwhelmed by a spray of Starro spores and controlled, and you must defeat him.
- In the final chamber is the Starro Conqueror:
- Whirlwind Attack: Starro Conqueror spins rapidly while on the move, dealing significant damage around it.
- Starro Double Beam: Targeted attack.
- Starro Juveniles spawn around the arena. They do not attack and can be attacked, but if you touch one you will become mind-controlled for a long time (about 45 seconds). While mind-controlled, your character will use weapon and power attacks against your teammates and their attacks can hit you as well. However, for the duration you are put in "out of combat" mode and will regenerate any health lost rapidly.
- In the final chamber is the last journal entry, whose author was the last survivor, trying to fight off the spores. It also reveals that he fights for something called " the Del...".
