Underpass was an arena featured in the Rocket Labs playlist in Rocket League. It had slanted walls and a higher ceiling, which allowed for a longer airtime for cars and the ball. It was added to the game on February 10, 2016.
On May 10, 2017, the arena has been removed from the game  but was added back to the game on July 8, 2017.
The first Rocket League arena to have multiple levels. Inspired by feedback from top-level players, Underpass features newly slanted walls and higher ceilings that lend to more hang time for aerial play.
