Bandai Namco released a free Dragon Ball Z: Extreme Butoden demo through the Nintendo eShop in Europe last week, and have since announced that it has already been downloaded more than 80,000 times.
Now regarded as a “massive success,” the publisher has announced that players can unlock a brand new Z-Assist character in Super Saiyan God Super Saiyan Vegeta.
In order to unlock the Saiyan Prince, players need only enter the corresponding code on the game’s title screen: XAB↓→↑YAR↓→↑A→R.
Dragon Ball Z: Extreme Butoden will release exclusively for Nintendo 3DS in Europe and Australia on October 16th, and in North America on October 20th.
