Detailed walkthrough
When the Sole Survivor gets close to Trinity Tower (the tallest building in Boston), the Sole Survivor will receive a distress call from Rex Goodman, who is trapped on the top of Trinity Tower. Once the Sole Survivor listens to the broadcast, the Sole Survivor will receive the quest Curtain Call.

Upon entering Trinity Tower, the Sole Survivor will be attacked by super mutants and mutant hounds. Over the loudspeaker the Sole Survivor will hear Fist taunt the Sole Survivor. Continue up the stairs to the elevator and enter to go up the tower. Once the Sole Survivor heads up the elevator there will be more super mutants in the area as well as mutant hounds. Go up the stairs to be taunted by Fist again. Once the Sole Survivor goes up another level the Sole Survivor will be confronted by more super mutants. On that level is the next elevator up. (There is an elevator shaft that the Sole Survivor can fall down that will bring the Sole Survivor down four levels into a room that has a safe with an advanced lock. This room can also be accessed by going down a level after the Sole Survivor exits the first elevator.

Having taken the second elevator up the Sole Survivor is almost at the top of the tower. Once again the Sole Survivor will face more super mutants, however there will be significantly more on the top so be prepared. Once the Sole Survivor gets to the top of the tower the Sole Survivor will meet Fist, who will carry a minigun and can be a tough boss if the Sole Survivor is not prepared. In the cage at the top the Sole Survivor will find Strong and Rex Goodman. They will be locked behind a master locked door however the key is in the Steamer trunk next to the weapons workbench nearby. Be sure to grab the Melee bobblehead in the cage where Strong and Rex Goodman are held.

Now that the Sole Survivor has freed them go across to the construction elevator on the side of the building and press the button. From here the elevator will take the Sole Survivor down a few levels but be careful because mutants will fire at the Sole Survivor and the elevator will stop on purpose.

Once the elevator stops and opens the platform to exit, fight the way down a level onto the next and final elevator. (Note that super mutants can throw grenades onto the elevator.) Once the elevator stops get off and work the way to the bottom of the tower the way the Sole Survivor came in. Talk to Rex Goodman to finish the quest, get rewarded with Agatha's dress if your character is a female, and Reginald's suit if your character is a male, and potentially get Strong as the Sole Survivor's new companion.

Reward

 * Reginald's suit (For male characters)
 * Agatha's dress (For female characters)
 * Strong (New potential companion)

Bugs

 * When taking the side elevator down the building the Sole Survivor's companion will often fall of the building or glitch however they should re-spawn as one leaves the elevator.
 * Rex will get stuck in the building and when you go up to save him he often won't come down.
 * Fix: pistol whip him until he runs to the exit of the building
 * If you die when confronting Fist and the other super mutants on the top of the building with the previous save being right before taking the elevator up to their floor, you will not be able to take the elevator up when you re-spawn. When you try to activate the elevator it will keep going up forever.
