Dragon Ball Z Budokai Cheats

After you complete the story mode you will be able to go back and do new missions in the three different sagas to unlock characters and items. After you do the new missions for each saga (can be done randomly), another mission opens where the story from the cartoon and game is changed. In the Saiyan Saga, you play as Vegeta and take on the Z Fighters. After Vegeta defeats each of them he turns Super Saiyan. In the Namek Saga, you play as Frieza and once again take on the Z Fighters. Once they are defeated Freeza, will use the Dragonballs and ask to be invincible. His wish is granted and he destroys Namek and then goes after Earth. In the Android Saga, you play as Cell. After absorbing Android 17, Cell goes after Android 18. He will try to absorb her but Krillin will jump in the way and be absorbed instead. Cell will become a hilarious fusion between the two. He will then take on Yamcha. After the fight, Tien goes to blast him but Cell suddenly wakes up from a dream. He is in his Perfect form waiting for the Cell Games. Additionally, these episodes can be unlocked when you complete Story Mode at any level:
