In Ultimate Ascent, 2013's game, teams had to shoot frisbees into high goals located above the drivers or into the top of pyramids in the middle of the game field. These frisbees were put into play by human players and robots and there could be up to four frisbees in play at once. In the autonomous period, robots try to score points by shooting the frisbees into high goals without the control or aim of a human driver. In the last twenty seconds of the game, robots begin to make an ascent up the pyramids that were in the middle of the field to make a final high score.
