Ultra is similar to the other Marble Blast releases in that the player uses first-person shooter style controls to navigate a marble through an obstacle course in a limited amount of time. It adds online multiplayer into the mix with 10 multiplayer levels in addition to its 60 single-player levels. The Mega Marble and Ultra Blast power-ups have been added as weapons to use against other players. Xbox LIVE Achievements are available for doing particularly well on particular challenges.
