Dragon Ball Z: Infinite World Hints for PlayStation 2
Not really much but thought it was pretty cool.
Ok go to Dragon Mission and go to Buu saga. Then go to the dot with Majin Vegeta on it(you must have SS4 Goku unlocked first) and put the "transform" capsule in.
The cutscene will play normaly, but when you have enough ki you can transform into SS4 and he will still have the halo.
Ok to make an easy win use someone with an attack that you can use right away like picalos special beam cannon. Charge ki to the max use the L2 botten to power up then keep presing up E and it will take like 900-2000 damage each time. They won't know what hit em. Theres also teen Gohans super Kamehamha. Hope I helped... Not rely.
