Super saiyan 4 Goku

In the buu saga before fighting super buu gohan absorbed go in the desert area there you would find ??? And then finishing there search around and there is mountains I think so or something like that and after that go fight buu gohan absorbed. Then after fighting buu nothing absorbed inside buu you would then go to a red mark on map and fight broly defeat him and unlock him. Then after that you would receive a note for fusing with vegeta and fight gotenks in the tournament. Instead of going to the red spot go capsule corp and talk to bulma then go to the world tournament and unlock gogeta along the way. Defeat gotenks and then instead of going to the red mark go to the small land masses or islands in easy words on the east of the bottom of the map and there you would find something. Go there and you would unlock ssj4 goku then go to the red spot on the map and then beat omega sheron to unlock gogeta ssj4. Hope that helps

All you need to do is get all the dragon balls with goku and shenron will show up with a list pick breakthrough goku and bam you get super saiyin 4 goku.

Please I also want to know what cheat we should active in super saiyan 4?

You have to use spirit bomb on kid buu when you are normal or kioken. Super saiyans do dragon fist(super).
There will be a continuation of du. Dont go to the red dot. Go to islands next to red dot. U will see a ???. Go there and you will get super saiyan 4 for goku(only on goku du). Save after you do this. Then do red dot and you will also unlock uub but it doesnt let you save some reason. Hope this helps!!!

You have to collect all dragon ballz in gokus dragon universe when you do finish his DR and select breakthrough

Get all the dragonballs for goku and then pick breakthrough out of the three things. While battling get all you're ki bars to max and prrss r2 and x together at the same time and you get ssj4

You have to do story mode if not then you have to use the dragon ball's

For beginners I would say is first go to that sand part . It will say mountains . Then you will talk to supremekai.He willsay it's a bigger power than superbuu. So fight superbuu. Then after that, vegeta will take kid buu on .so you go to the red part of the mountains fight broly . After you fight him you will unlock broly for dragon universe.then goku will get a note saying fusion battle.but first find all dragon balls. Then fly around the island until you see ???. Then you will unlock ss4 goku.so go to the world tournament, do fusion with vegeta beat gotenks then it will take you on from there .

You have to have breakthrough (goku only) have your ki gage full then press R2 and X at the same time and you will be super sayian 4 (goku only)

Be goku in the dragon univers than get the dragon balls than beat the DU univers with goku than wish breakthrough (goku)than you will have super saiyan 1,2,3,and 4 hope that helps
