When Pathfinder Ryder is traveling west of Prodromos in The Sheartop, a stranger makes contact over comms claiming he knows how to beat the kett and invites Ryder. (A map marker will indicate the location in Presson Dunes.)
Meet The Contact Edit
Destroy A Power Generator Edit
The generator is inside a larger bunker next to Massani's bunker. Eliminate the kett and use the console to shut down the generator.
Ryder receives +540 XP, +29 AVP , and +2% Eos viability.
Destroy The Barracks Edit
The barracks are uphill, south of the Forward Station. Eliminate the kett forces to complete the objective. The kett have the advantage of higher ground and better cover, but luckily don't use it especially well.
There is a datapad in the barracks:
Speak With Bain Edit
Return to speak with Bain. Bain congratulates Ryder on a job well done.
- +270 XP
If Ryder happens to clear the barracks outpost (or the main Kett outpost) before the mission is given, for some reason the barracks outpost will not be marked on the map, and Ryder will be unable to interact with Bain. To fix this issue, get away some distance or reload a prior save.
