Sounded Like Engines is a short mission in Bend Studios’ Days Gone.
Your task is to simply get to the watch tower and check if there are marauders around.
Here’s a walkthrough of Sounded Like Engines in Days Gone.
This mission is part of the “He’s My Brother” storyline.
Climb the tower
The mission starts automatically after you’ve completed the previous one. Get out of the bunker and climb the tall watch tower in the compound.
It takes quite some time to actually get up there.
Look at the O’Leary Mountain Safehouse
As Boozer mentioned that there is some activity around the safehouse, look towards that direction. This part is probably done automatically.
The mission completes after you’ve found some activity. That unlocks the next quest.
You will get 2,000 XP for completing this super brief mission.
