Which Psyonix mobile game inspired Rocket League's Starbase ARC update?

Starbase ARC was inspired by Psyonix’s mobile game ARC Squadron. The Rocket League arena debuted in December 2016 as a free space-themed addition, featuring an octagonal station orbiting a desert planet.

ARC Squadron was itself a Psyonix-developed science-fiction shooter released for mobile devices. Its space setting and visual identity gave the Rocket League arena a clear internal connection to the studio’s earlier work, rather than making it simply a generic science-fiction map.

A common mix-up is Halo: Starbase ARC’s ring-like space setting can evoke Halo imagery, but the arena’s documented inspiration was ARC Squadron. The arena was later redesigned for standard play and renamed ARCtagon, while the original Starbase ARC layout remained associated with Rocket Labs-style gameplay.
