This achievement is story related and cannot be missed. The achievement is unlocked at the end of Chapter 14 during your third playthrough
Playing as A2, when you finish the next to the last main story mission in chapter 14, Village Turmoil, you are instructed to travel to the Abandoned Factory. Fast travel to the Abandoned Factory Entrance and make a save
at the access point. You will not have another opportunity to make a save until after the conditions for unlocking the achievement have been met. The achievement will unlock when you finish the following and final main story mission of Chapter 14.
If you finish the chapter without unlocking the achievement, you have probably experienced a glitch. In the event of a glitch, clear the cache. To do so, turn off the console by holding the
button on the console for at least ten seconds and then unplug the console for at least 20 seconds. Load the save you made at the Factory Entrance access point. Clearing the cache will most likely remedy the problem and the achievement should unlock when you replay the end of the chapter.
