Hoverboard racer where Sonic and crew compete on customizable Extreme Gear boards. The core twist: gravity manipulation replaces traditional fuel. Build Gravity Points through tricks, then trigger Zero-Gravity Zones to warp physics—Gravity Dive creates a black hole pulling you forward while sucking nearby objects into your path for extra speed, or Gravity Control flips track sections to reveal shortcuts. Gravity Drift handles tight turns. Story involves ancient relics called Arks of the Cosmos that control gravity, which accidentally give sentience to robots that go berserk. You'll race the rival Babylon Rogues while chasing these artifacts across tracks, eventually fighting a transforming robot boss. Campaign mixes racing with chase sequences. If you want arcade racing that bends space rather than just going fast, this delivers that specific hook.
