In the Salty Shark Uprising Saltyverse, the mermaids and sharks hone their skills for battle against the Atlanteans and Sea Pirates. One such testing ground is the Atlantis Sub Racing Circuit, where captured Atlantean subs are put through their paces! Test your skills and record the best lap times. Collect crystals to unlock new sub models (SSU Holders) and soon, battle your friends in multiplayer races as well! Master this course, because additional circuits are being uncovered as we speak.
