Rad Resist.png Parsons State Insane Asylum is under attack and Jack Cabot asks you to help him suppress it. You may follow along with him on his journey to the Asylum learning some interesting back story on the way or you may meet him outside the main entrance to find a Raider onslaught. Enter with Jack and remove the enemies from existence. Unchain the door at Jack's office and go in.

Rad Resist.png Raiders have reached the basement, keep progressing through with Jack into the asylum. Go down the portion of floor that has collapsed. Go to a hole behind the wallpapered wall and drop down. Find the elevator and take it to the basement.

Rad Resist.png Follow Jack into the basement lab where Raiders are attempting to free Lorenzo Cabot. Go through the doors, eliminating Raiders along the way. Loot the body of Lefty to obtain Mysterious Serum 4x. Jack will ask you to access the generators on each of the walls, and set 2 to manual override. Lorenzo is begging to be freed.

Rad Resist.png If you opt to keep Lorenzo locked up, set the last 2 generators to manual override so that Jack can flood the chamber with Zeta radiation and speak to Jack. He will thank you and reward you. Return to the Cabot House in one week and he will give you the unique weapon Lorenzo's Artifact Gun. He will only give you this if you are polite to him during the entire quest.

Rad Resist.png If you free Lorenzo, he will escape and tell you he is going back to the Cabot House with murder on his mind. You can opt to warn the family of his return and help them defeat him. A week later return to Cabot House to receive the Lorenzo's Artifact Gun. If you opt to aid Lorenzo in the murder, Lorenzo rewards you with the Mysterious Serum.
