Power Play

Power Play is a quest and achievement/trophy in the Fallout 4 add-on Nuka-World.

Quick walkthrough
After getting three raider settlements, a quest pops up telling you to talk to Shank. He sends you back to Nuka-World with news of a revolt by the leader of the gang, whom you gave the least land. You must meet with the other leaders to retake the Nuka-World power plant, and after a small chat and you storm the plant with the other two. Fight your way to the roof where you kill the rogue leader. You then go to the power control room and flip the switch to bring power back to Nuka-World in full.
