Once the Sole Survivor has been welcomed to Acadia, talking to Dejen on the first sublevel will eventually bring up the topic of an Institute Courser presence on the Island. Dejen claims the courser tracked Chase all the way from the Commonwealth because she "screwed up" during her last visit there, and he tasks the Survivor with hunting down and eliminating the threat to Acadia. The target can be found at a radiant location somewhere on the Island. Once the courser lies dead, returning to Dejen ends the quest with a reward in caps.
- Often when arriving at the Courser's location, he can be found fighting multiple trappers. This may make the battle slightly easier, but it is not uncommon for them to team-up against the player character.
- This quest can be obtained regardless of the Institute's condition or fate from the main quest in the base game.
- Old Longfellow dislikes it if the Sole Survivor accepts this quest. He also dislikes the Sole Survivor boasting to Dejen about having defeated Coursers before (if applicable during dialogue).
- If you speak to the Courser prior to entering the Institute he will respond as if you already have.
- pc xboxone ps4 After killing the Institute Courser, the Sole Survivor could be unable to speak to other NPCs, starting line being constantly "Hey, Dejen". To fix this, just end the quest by speaking to Dejen again. [verified]
- pc Mission fails to start, ever. Dejen does not initiate quest dialog.[verified] This can be seen if it applies by typing showquestvars DLC03AcadiaM02 this will show the quest as stopped if the glitch applies. It can be fixed by using the command SetStage 04049b 10. This will start the quest start dialog.
- pc Sometimes after arriving at courser's location you may find him fallen through the terrain. To fix that, enter tcl command to disable clipping, float to courser to target him (move closer and click on him, you'll see his RefID on top of the console area), float back slightly above surface and enter "moveto player" command. This will teleport the courser to player location, and thus, above the surface. Save the game, revert clipping mode to normal and reload the saved game.[verification overdue]
