When Freedom Calls

When Freedom Calls is a quest and achievement/trophy in Fallout 4.

Detailed walkthrough
On the travels through Concord, the Sole Survivor will spot a man protecting a group of people from Raider attacks on a balcony of the Museum of Freedom. Below the balcony is a short laser musket and some fusion cell ammunition in front of the doors. Pick it up if interested in disintegrating the enemies, and clear any foes from the streets. Then enter the Museum.

Fight your way through the raiders, and head upstairs. On the second floor, meet Preston Garvey and the remnants of his Minutemen forces. While the Sole Survivor is here, be sure to pick up the Perception bobblehead and the RobCo Fun magazine, containing the Atomic Command holotape. Agree to help him and Sturges provide fire support to crush any remaining Raider opposition in town. Drop to the ground floor and into the basement. From here, one can choose to either hack the terminal to unlock the door, or directly pick the lock on the door. Both are of novice difficulty. Either way, once having opened the door, grab the fusion core inside.

Once having the fusion core, head upstairs and onto the roof to find a suit of T-45 power armor. Insert the fusion core into the power armor, and climb inside the suit. From here, one can take the minigun from the vertibird. One can either jump off the roof, or stay on it for a little while. Either way, start killing the enemies on the ground. When killing Gristle, the only named raider, be sure to pick up the Corvega storage key off of his body. Once having killed a considerable amount of raiders, a deathclaw will appear. Although it looks menacing, it is relatively easy to defeat with both the minigun and the power armor. The deathclaw can do a lot of damage, however, so be cautious. Once having defeated all of the enemies, enter the Museum of Freedom and speak to Preston to complete the quest.
