The agility course is one of three exercises at Camp McClintock the dweller needs to complete as part of their basic training.
Select "Begin Course" on the Agility training terminal at Camp McClintock. Follow the quest marker to the Obstacle Course terminal, then select "Begin Course" on the terminal to start the quest. After a short 15 second countdown, the player will be given 2 minutes to complete the course.
The course consists of 7 obstacles which must be completed in order, starting with the tires. Each obstacle requires one to push a button at the beginning and end of the obstacle, both buttons are marked with quest markers and most have at least one quest marker in the middle of the obstacle that the player character must pass through. Once an obstacle is completed, the next obstacle will be marked. Once the course is finished within the 2 minutes allotted, the quest will be complete.
If one fails to finish the course within 2 minutes, they can restart the quest from the obstacle course terminal. This quest can fairly easily be completed, even while overencumbered. The course is a test of effectively using the navigation keys and the time limit is quite generous. With the crosshair enabled, balance beams are trivial - without it, slightly more challenging.
