Complete walkthrough for the Fallout 4 'Show No Mercy' quest. Learn how to clear Fort Strong, defeat Super Mutants, and secure valuable loot for the Brotherhood of Steel.
Walkthrough
- 1After meeting everyone on the Prydwen, find Elder Maxson on the bridge. He will task you with clearing out Fort Strong, which is overrun by Super Mutants and holds an armory of Mini Nukes.
- 2Board the prepped Vertibird and fly to Fort Strong.
- 3As you approach, use the Vertibird's Minigun to destroy the Super Mutant Behemoth.
- 4The Vertibird will land. You can stay in it to eliminate smaller Super Mutants with the Minigun, or bail out if you attract too much attention from leveled Super Mutants or grenades.
- 5Once the area is clear, loot the Super Mutant corpses. Be cautious of radioactive barrels inside the houses.
- 6Head to the north side of the island, cross a bridge, and enter the guard shack-like "entrance building." Inside, you can find a suit of Power Armor, possibly an X-01.
- 7On the east side of the island, find a dock with a Caps Stash. There may also be some random Mirelurks.
- 8Enter the main building, the "Fort Strong Armory."
- 9In the first room, fight through Super Mutants. You can jump up rubble to the upper floor for junk.
- 10Proceed through the left room and into the office rooms, clearing out four Super Mutants.
- 11Continue to the back room. An elevator is to the left (to be used later). To the south are more rooms with three Super Mutants; clear them out. A first aid kit is in the bathroom. The room on the left has rubble to access the second floor.
- 12Grab the two ammo boxes on the table. The door on the right (in the corner) is locked [Novice] and leads back to the entrance.
- 13The other door in the back is also locked [Novice]. Pick this lock to enter "General Brock's Room."
- 14Inside General Brock's Room, loot the army box, find the "Fort Strong Key" on the desk, the **U.S. Covert Operations Manual** skill magazine (permanently boosts sneaking), a Mini Nuke, and a safe.
- 15Return to the elevator and take it down to continue clearing the armory.
- 16In this final area, check the left room for a first-aid kit and the right room (bathroom) for Purified Water in the toilet.
- 17Below the balcony, sneak attack two Super Mutants and their two Mutated Hounds.
- 18In the rooms below the balcony, and down the north hallway, kill three more Super Mutants. Be aware that one has a Missile Launcher.
- 19After clearing the armory, explore the east and south rooms for junk.
- 20In the north hallway, the right room contains the "Bravo Team Testing Terminal." The left room has more junk. Further in, find two Mini Nukes and an open armory door with an Ammo Box and a First Aid Box.
- 21Talk to Paladin Danse to continue. Agree with him for a "Danse Loves That" notification.
- 22Report back to Elder Maxson on the Prydwen. He will be pleased and give you eight Vertibird Signal Grenades. The mission ends after your conversation.
- 23Elder Maxson will then discuss the Institute and ask you to locate them. You can now bring up the Signal Interceptor.
- 354 XP for clearing out Fort Strong.
- Eight Vertibird Signal Grenades from Elder Maxson.
