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 a leader of the three gangs who took the power plant. You must meet with the leaders of the other two to retake it. Small chat and then you storm the power plant with the other two factions heads. 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.
