Enjoying the new DLC. I was worried it will be dull like automatron, glad to not be disappointed with it. Spoiler If you sided with the institute in the main campaign, they can be faction #4 (kinda). I got to inform the institute on Acadia during the main dlc quest and they've now set up a relay on the island and waiting for my order to begin an attack. Damn. Still got a bit to do before I finish the main quest and see how that goes.
