Dragon Ball Z: Supersonic Warriors 2 Unlockables (DS)

Dragon Ball Z: Supersonic Warriors 2 is a video game based upon the popular anime series, Dragon Ball Z. Supersonic  Warriors 2 is a sequel to Dragon Ball Z: Supersonic Warriors and was developed by Cavia and published by Atari for the Nintendo DS. It was released in 2005. Story Mode in Supersonic Warriors 2 consists of a board game-like adventure. In this mode, you enjoy an individual character's story as Goku, Gohan, Krillin, Piccolo, Vegeta, Trunks, Goten, Ginyu, Frieza, Dr. Gero, Android #18, Cell, Buu, Cooler, and Broly travel around the 155 different levels defeating enemies. There are adapted and original "what-if" storylines that allow characters to power up.

This game profited from the huge popularity that this franchise has everywhere around the world, being one of the few anime series which enjoyed success not only in Japan. It had very big sales and brought Atari, its publisher back from the very troubled times it had.
