The real pay-off of Marble Blast Ultra is in the swear-inspiring multiplayer. You probably want to turn your headset to mute during these matches as the action gets frantic enough to encourage streams of ear-blistering curses from even the most level-headed gamer. In a full 8-player game, the competition is ferocious with all eight marbles vying for a few precious red gems. Once you grab 'em, another set appears (usually on the other side of the map) and it's another mad rolling dash to collect more. Matches typically end up looking like someone dropped a stick of dynamite in a sack of marbles, only in reverse, because everyone converges on the gems. It's so simple in concept, but so rewarding to actually pull-off a win.
