A Dashing Individual is a quest given by Apex Scientist Elliott in the Tech Lab after completing Let's Get Technical.
After accepting the quest speaking to Elliott again will give the option to teleport to a tech challenge course. In this course the dash tech is automatically enabled, players need to activate switches then double tap a direction to dash through gates and reach the end of the course. Along the way there will be a variety of obstacles and traps, but there's no mortal danger inside the course.
At the end of the course is a teleporter back to the outpost. Once back there the dash tech will be available for use, as well as a variety of available upgrades for it at the console in the tech lab.
