Kept Secret But Not Forgotten is a quest from the main storyline which is available regardless of the chosen path - Phineas or Halcyon. During its duration, you will have to decide which side of the conflict to choose. This page of The Outer Worlds guide offers a walkthrough for this quest.
List of objectives
- Travel to the Hope;
- Repower The Hope's skip drive
- Patch ADA into the Hope'scommunications systems.
- Perform a skip with The Hope;
- Return to your ship (Halcyon's path)
- Head to Phineas' lab (Phineas'path)
This task is unlocked once you've completed one (or both) of the following quests: Foundation, and The City and The Stars. In both cases, you will have to go to The Hope. Here comes the choice - each of the sides of the conflict want to skip to a different location - Phineas to Terra 2 and Halcyon to Tartarus.
As soon as you get off the ship, go towards the terminal, located nearby. Using it, you can reset The Hope's systems. Now travel to Duncan. Convince him to open the room that contains the UDL staff ID. If the check isn't successful, you can also pick the lock on the door.
Now proceed to the restricted area. Turn into the corridor found on the left side of the hall. Go through the door and turn left again. You'll reach a room with a terminal which allows you to establish connection with Unreliable. The same room contains a key to the bridge that will allow you to continue forward.
After leaving the room, go straight. You'll reach an elevator that will deliver you to the bridge. You can make the jump from there. This is the moment when you decide which side of the conflict you want to stand on. If you support Phineas, then Hope must skip to Terra 2, and if you want to support the Halcyon, then you have to skip to Tartarus. Depending on your choice, the rest of the task will go differently.
Skip to Tartarus
If you decided to travel to Tartarus, your task will be to return to Unreliable Once you're up there, you will speak to Chairman Rockwell, and the task will be completed.
Skip to Terra-2
As soon as you decide to side with Phineas, the scientist will be caught. Travel to his lab. Enter the room which was earlier inhabited by the scientist - you'll find a secure terminal there. Search the pig's body lying on the table to find a password.
Use the terminal to open up a cache located in Phineas' bedroom. In it you will find a navigation key giving you access to Tartarus. Now you're able to fly to the planet, and the task will be completed.
