Kill the targets in Mass Pike

Use the yellow elevator to reach the hideout

The quest has two main parts. In order to unlock the first one, you must gain only few approval points from MacCready. It can be easily done by stealing (especially the items in buildings). Once you gather enough approval, MacCready will initiate a conversation with you.

During the first part of the quest you must get to Mass Pike Interchange where a group of mercenaries have their base on the highway. To reach it you must find a yellow elevator underneath. Above, in addition to regular enemies, you will face one opponent with a power armor and two key enemies - Winlock and Barnes whom you must kill (they are your only objectives).

Go to the Med-Tek laboratory and obtain the cure

After killing the targets you must walk a bit with your friend and gain more of his approval

Once you complete the first part of the quest, keep traveling with MacCready and gain his approval. After a while you will learn that his son is sick and that you must find a cure for him. It can be obtained in the Med-Tek Research, in the basement.

MacCready will give you access to the terminal

The whole laboratory is occupied by various ghouls. First you must use the collapsed ceilings to reach the highest floor. In one of the rooms there you will find a working terminal. Once you walk towards it and eliminate the enemies in your sight, MacCready will give you the password to the computer. Now you can go to the ground floor and use the second terminal.

In the basement you will find stronger ghouls than the ones in the main building

After walking through the corridor you must reach the basement using the elevator. There is a locked laboratory on the lower level. Inside there are many ghouls, so it is worth to prepare a trap for them at the door. The cure can be found in that room, on the table in the middle. You can return to the surface faster by using the elevator in front of the entrance to the laboratory.

Deliver the cure to Daisy

Daisy in Goodneighbor

The last phase of the quest is going to Daisy the shopkeeper in Goodneighbor. After a short conversation the quest will end. It might happen that you won't be able to give the medicine to Daisy until you complete side quests for her.

Quest rewards: Experience points.
