The Outer Worlds includes Companion Quests that are optional to complete, and are played through to strengthen the relationship with non-player characters (NPCs) in the party.
Each companion has their own quests, some more than one that not only rewards players with good loot, money and XP but could also potentially unlock more quests.
Friendship’s Due Quest Guide
This Companion Quest will only be available if you recruit Felix. Go exploring with Felix, where you will have to wait for a brief amount of time and then talk to Felix, who will ask you for a favor. Accept his request to start the quest.
Go to Harlow’s Base in Scylla to meet with Harlow. You will have to travel to the landing pad to have a chat with him. Felix will only be allowed in Harlow’s crew if Felix can kill Rufus Trask, who’s a traitor. You will have to find the traitor, kill him and loot his ring.
To find Rufus Trask, you will have to talk to his wife, Rosana who can be found on the Groundbreaker. She will tell you that her husband is hiding in Emerald Vale. Head to Emerald Vale and go north-eastwards from the Botanical Lab, to North Gulch.
Here you will find Rufus Trask, you will get to know how Harlow is a board asset who is engaging in a sanctioned policy by the board. This is when you will require proof from Rufus Trask, and you may let him live and take his ring.
After this, go back to Harlow’s Base, consider picking up the Stashed Receipts on your way to get extra XP. You will talk to Felix, who will be very surprised.
After you’re done talking to Felix, speak with Harlow and tell him about what Rufus Trask said and show him the evidence. He will refute the accusations, which is when you can make use of perception and point out that Harlow lied about Rufus Trask working for the board.
You will point out how this does not make sense and Harlow will attack you after losing his patience.
Finally, talk to Felix to complete the Companion Quest. You will get forty-three thousand (43,000) XP, and thirty-six hundred (3,600) Bit Cartridges along with Harlow’s Emblem.
