Soundtrack Attack was a Steven Universe mobile rhythm runner game that was released on July 21, 2016. The player's customized Gem character (either a Ruby, Pearl, or Quartz) has escaped from Homeworld via an escape pod, and with the help of the Crystal Gems, must travel along various locations to avoid being captured by Homeworld Gems in a Roaming Eye. The game was taken down from app stores in late 2019 for unknown reasons.
