Contact Responders Quest
Head out of Delbert’s house and start walking around town. Look for a Brahmin to kill and loot, or a Brahmin corpse if you don’t want to hurt any animals. Take the meat to the cooking station down the street from the Command Post and cook it to obtain Ribeye Steak. With the steak in hand, head back to the Self-Serve Kiosk and select the “Complete Training” option on the terminal.
After completing your training, head across the street to the Command Post and find the Responders Database terminal just inside. Log into the terminal, then select “Volunteer”, then “EMERGENCY: Contact Responder’s HQ”. This will complete the quest, and automatically give you access to the next one, Final Departure.
