Patrick Larsen is an inhabitant of the Agricultural center.
Patrick Larsen is seen by many as one of the most brilliant minds in the agricultural center. A talented doctor, researcher, and inventor, he was accepted with open arms. Unbeknownst to others, he is a plant sent there by the Children of the Citadel to wreak chaos on Arizona before the robot invasion. By the time the Rangers get to him, he fakes being injured in order to lull them into a fake sense of security.
- Shut down the irrigation to halt the spread of infection: Larsen is the end boss of the agricultural center. The player has to confront him and kill him in order to finish containing the infection. Note that as a synth, he explodes on death. He is a formidable character, as he has over 200 hit points and uses the reasonably powerful Midnight Special.
- If the Rangers chose to save Highpool, then Larsen will be found executing the Wounded Gazelle Gambit at the console in the Central Complex. After a brief interrogation, he will attack. The player can force him to do so, using a Smart Ass 2 check, followed by a Hard Ass 4 check.
