The Outer Worlds The City And The Stars Quest Walkthrough

In The Outer Worlds, players traveling to the glitzy city of Byzantium on Terra 2 will encounter one of the main narrative turning points in the quest titled The City and the Stars. Sent by Dr. Phineas Welles to acquire a supply of dimethyl sulfoxide, your crew must navigate political intrigue, corporate security, and moral dilemmas. Completing this mission requires a balance of stealth, diplomatic skill, or raw firepower depending on your preferred playstyle.
Reaching Byzantium and Infiltrating Minister Clarke's Estate
Upon landing in Byzantium, your first objective involves gaining access to Minister Clarke's heavily guarded residence. Players can acquire an entry key by getting Guard Mayfield intoxicated at the local bar or by retrieving a postal package from the nearby courier station. Bringing the package directly to the guards allows you to enter the estate without provoking a violent citywide reaction.
Infiltrating Halcyon Holdings Headquarters
Once inside, Minister Clarke reveals that Chairman Rockwell has been forging his authority and holding the colony's chemical reserves. He grants you his access card, which opens doors inside the Halcyon Holdings Corporation building. You can sneak through the maintenance tunnels or use your corporate disguise shroud to reach the upper offices and print the necessary Ministry keycard.
Securing the Dimethyl Sulfoxide in the Ministry Labs
With the keycard in hand, head to the Ministry of Accuracy and Morale to reach the underground research laboratory. Equipping a valid UDL disguise allows you to move past patrol guards while searching for the chemical storage terminal. At the main terminal, players must decide whether to extract the full batch of dimethyl sulfoxide or save the lives of the test subjects inside.
Escaping Byzantium and Reporting to Phineas
After acquiring the chemical canister from the terminal, exit the laboratory using the nearby shortcut elevator. Return to the Unreliable and plot a course back to Phineas Welles' hidden lab in deep space. Delivering the chemicals concludes the quest, awarding substantial experience points and unlocking the next phase of the main story.
