Here’s a walkthrough of It Was On Me in Days Gone.
Visit Sarah’s memorial stone
Your one and only task for this short mission is to go north of Hot Springs camp.
Go back to Sarah’s memorial stone near the helicopter.
When you get there, you may encounter some freakers walking around.
You can probably avoid most of them and just go through the vehicle you moved in an earlier mission.
Go past the vehicle and you should reach the memorial stone right away.
Get to it.
Deacon will then have a monologue with Sarah.
The mission completes here. You’ll get 2,000 XP for this mission.
