The Outer Worlds: Spacer's Choice Edition

You unlock the achievement by reconciling the differences between mother Olivia and daughter Minnie during the final main quest mission, The Ambrose Intersection. You will arrive at this mission through story progression, but there are four possible endings. This achievement relates to one of those four endings: Achieve a compromise to bring about a Family Reunion.

The other three endings are:

To have access to all four endings, make a save as soon as you get to The Red Tape of Command main quest mission. This is the second to the last main quest mission where you must retrieve a journal. The Postman ending requires a specific action to be performed before the journal is retrieved. The Postman ending precludes obtaining this ending (unless one does some save manipulation). So, to get both this ending and the Postman ending on a single playthrough, make a save file at the decision point BEFORE the journal is obtained.

I recommend doing the Postman ending first. If you have not previously activated the reactor, the Postman Path will also unlock the Greenlight Protocol achievement. The following is a detailed guide: Solution for The Postman In The Outer Worlds: Spacer's Choice Edition

When you start the Ambrose Intersection mission for the purpose of getting this achievement, make sure you have persuade at 150. A high persuade is not required for the other three endings.

Basic persuade need not be high. My character's basic persuasion was only 52 (with very high intelligence & temperament & good charm. However, with the armor master perk that doubled equipment bonuses, I boosted persuasion to 153 as follows:

• Cashier, Sub-Grade: +1
• Wearing the Chimaera +20
• Wearing the Nice Hat +14
• Caffeine Drink +5
• Felix wearing Dialog Skills +5 armor with Dialog skills +10/Leadership Skills +10 kit & persuade +5 helmet: +26
• Parvati wearing Dialog Skills +5 armor with Dialog skills +10/Leadership Skills +10 kit & persuade +5 helmet: +25
• Felix Perk Bonus Support Persuade: +10
• Tip: If you include a caffeine drink in the inhaler, you can instantly get Mind +1 resulting in Persuasion +5 by pressing as you approach a character with whom you are to have a dialog.

Note: The Chimaera and the Nice Hat are acquired when you get the Well Dressed achievement.

If you can't get persuade to 150, you can reset your skills aboard your ship in order to meet this prerequisite.

With 150 persuasion, go to Minnie at the Ambrose Mansion. There will be mission objective markers on both Minnie and Olivia so make sure you follow the objective marker for Minnie at the mansion and not Olivia at the Synthesis & Manufactory Center (SMC).

As you approach your objective be prepared for the dialog to start abruptly. If you need to, ingest a caffeine drink when you are a few meters away. As you begin the dialog with Minnie, immediately suggest a compromise as soon as the option becomes available. The dialog differs depending on what your character has discovered during the game. Be positive and work towards reconciliation. This is a sample dialog, yours might differ slightly:

--What if you & your mother joined forces to cure the marauders.
--[Persuade 65] If the marauders don't get a fix, they'll just rampage across the galaxy.
--[Persuade 100] Why not give her a chance, she's been involved with Adrena-Time since the start.
--[Persuade 150] The Adrena-Time project failed, you couldn't have saved it.
--Opportunities present themselves every day, your Gorgon will come.
--This isn't failure, this is a second chance to work with Olivia.

Minnie will say that maybe her family deserves a second chance. At this point, you will have three options for the Ambrose Intersection Mission:

1. Restore power to the Adrena-Time reactor
2. Activate the NDA protocol
3. Find a compromise between Minnie & OIivia

In other words, if you make a save file here, you can use it to get three of the four endings. If you want the NDA Protocol achievement, just walk up the stairs to either your right and left and go to the terminal behind Minnie. She will protest, but you can use the terminal and activate the NDA protocol unlocking the achievement.

However, to complete the compromise, we must go to Olivia. Return to your ship and go to the Gorgon Landing Pad. From there, go to the SMC facility. If you had befriended PAM before, talk to her. She will be right inside the entrance to the facility and will again lead you through the facility helping to eliminate hostiles. She will stop next to the elevator that leads down to Olivia.

Alternatively, you can make your own way through the facility, eliminating hostiles as you go. When you exit the elevator, use a caffeine drink if you need a +1 mind boost, open the bay door & a smaller door in front of you, and go forward to trigger the dialog with Olivia. Yours might be slightly different but here are some possible dialog choices leading to reconciliation:

--Whoa, hold on! I'm here to make peace!
--Let's take it down a notch.
--Your daughter's agreed to a compromise.
--[Persuade 45] You don't. You just have to trust me.
--She said you were invited to tea?
--Explain
--So you'll work with Minnie.

There are differing scenarios that work. Nevertheless, providing that you choose positive responses, eventually the other person will acquiesce and the achievement pops. The Ambrose Intersection Mission is complete at this point. You get a green check mark in the reconciliation option and red checks in the other two options. Return to the mansion for a short dialog with Minnie and Olivia to finish the Peril on Gorgon questline and pop the achievement. Dialog choices do not matter at this point.
