The game follows the Saiyan Saga of the original DBZ story starting from the World Tournament and Goku's triumphant defeat of Piccolo. Players will take the role of Goku and travel the DBZ universe from jungle to Snow Mountain on their quest to victory.

Help Goku and his Earth Defense Force allies tackle the ever increasing apocalyptic alien threat to their planet with martial arts action. In addition to taking place within the Dragon Ball Z lore, Dragon Ball Z: Attack of the Saiyans will feature numerous never-before-seen alternate storylines which offer a new understanding of the Dragon Ball universe.

Dragon Ball Z: Attack of the Saiyans features a three character party system where players can choose from Dragon Ball Z's iconic roster of Earth Defense Force heroes including Goku, Kid Gohan, Piccolo, Krillin, Yamcha and Tien to tackle the sinister Saiyan threat. Unique to Dragon Ball Z: Attack of the Saiyans, the team combo attack system enables players to combine the awesome might of each party member's super martial art attack to inflict massive damage onto enemies. Also, each party member will feature character specific Ki Blast abilities which will be used to solve puzzles and unlock secrets in the game.

Additionally, Dragon Ball Z: Attack of the Saiyans will offer a sub-mission mode where players are tasked to collect special items, including the legendary Dragon Balls, throughout the world to rescue innocent victims, right worldly injustices, and create general global harmony. Completing righteous assignments will offer major rewards with mysterious results.
