Variable Removal is a Railroad radiant quest in Fallout 4. It requires the Sole Survivor to go to a random location and eliminate a Courser. If left unchecked, a Courser could cause a lot of damage to the Railroad's infrastructure.
1. Eliminate the Courser
The Pip-Boy will have been updated with the location of the Courser (they are different random locations). Travel to that location and eliminate the Courser however necessary. The only kill required to complete the quest is the Courser's, but all of the synths can be destroyed at this location without turning the Institute hostile.
2. Report back to Predictive Analytic Machine
Return to P.A.M. at the Railroad HQ. She will congratulate the player character on a job well done and give bottlecaps or sometimes a weapon as a reward.
- When initiating this quest, P.A.M.'s dialogue will differ depending on whether or not the Institute has been destroyed.
- When the Institute is friendly to the Sole Survivor, killing the Courser does not make them hostile, although it is still considered to be a murder and will be registered as such in the crime stats.
- It is possible for this quest to point to a location in an installed add-on.
- In Survival mode P.A.M. states that there are three Coursers to be removed, and she does not give any more quests after the third courser is killed.
- Sometimes the quest will not be given again once completed, likely due to an error in the radiant quest system.表达式错误：未预料的<操作符
- If P.A.M. is reprogrammed and brought back to the Prydwen after the completion of Tactical Thinking, the quest will still be given as if you are still a member of the Railroad.表达式错误：未预料的<操作符
- One can use the console command setstage 00186c79 300 to fix this.
- The radiant target may sometimes fail to change and can become locked into one location, e.g. only ever having the courser appear at University Point and not at any other location.表达式错误：未预料的<操作符
- If the target location is the RobCo Battlezone, the courser may spawn beneath the arena and cannot be reached to complete the quest.表达式错误：未预料的<操作符
- It is possible to use the console command MoveToQuestTarget <QuestID> to teleport to the Courser and then to P.A.M.
