In Rainmaker, opposing teams battle for control of the Rainmaker, a powerful weapon lying in the center of the stage. Whichever team succeeds in carrying the Rainmaker to the pedestal located in the opposing team’s base will taste the sweet nectar of victory. If you charge the Rainmaker up all the way, the shots it fires will explode when they reach their target! In Rainmaker, the best defense is a good offense, so don’t hold back!
