Starfield The Key Ingredient Walkthrough
Talk to Masako
Head into the Ryujin HQ Elevator to the Research and Development department. Masako will brief you on her plan to deal with Infinity Ltd.
Meet Veena Kalra
Talk to the head of the department, Veena Kalra. She'll mention the need for Rothicite and a shipment that has been delayed.
If you did Nyx a favour in the previous mission, Background Checks, Camden will not attend the meeting.
Travel to Carinae III-A
Travel to Carinae III-A in the Eta Cassiopeia Star System. Land at the CM Station RC-1.
Enter the CM Station RC-1 Mine
Once you reach the mine, you'll find that all the workers are missing, and Ecliptic Mercenaries are crawling all over the place. A handful of enemies are blocking the entrance to the CM Station RC-1 Mine. Take them out.
Discover What Happened at CM Station RC-1 (Optional)
Making your way through the CM Station RC-1 Mine is challenging as it's sprawling with high-level Ecliptic Mercenaries and explosives littered everywhere. The path is also quite narrow and dark, making navigating and finding cover hard.
Once you reach the end, you'll run into an Elite Ecliptic Mercenary. Once you defeat him, you can pick up some secret orders from his body.
Find the Rothicite Shipment
You can interact with the computer in the room to see what happened to the various Rothicite shipments. The only one dispatched was one headed for The Clinic.
Read the Contract
Read the orders you found on the Elite Ecliptic Mercenary, and you'll find out that Infinity Ltd. was responsible for the slaughter at CM Station RC-1.
Travel to the Clinic
Make your way to the satellite known as the Clinic in the Narion Star System.
Enter the Secure Wing
You'll need to gain access to the Secure Wing. A Freestar Guard is blocking your access. You can deal with him in the following ways:
- Use the Medicine skill dialogue option to be let through.
- Use Persuasion for a 6-bar check.
- Bribe him with 2500 Credits.
- Pickpocket the keycard using Theft.
- Talk to Ari Miller, the receptionist, and pretend that Dr Oslan needs you.
Retrieve the Rothicite Shipment
Once inside, you can talk to Sean and Dr. Lane, who will be arguing. You need to gain access to their computer or have them tell you what's going on. Here's what you can do.
- Use the Medicine skill dialogue option to guilt them.
- Lie to them about being from Infinity Ltd.
- Wait for them to leave and hack the computer with Security.
- Use Persuasion to get what you need.
- Defeat the guards who show up.
Once you've dealt with them, you can access the files on Dr. Lane's computer and pick up the Rothicite Shipment lying on the desk.
Give Rothicide to Veena at Ryujin Tower
Head back to Ryujin Tower in Neon City. Go back to the R&D department and hand over the Rothicite to Veena.
