Unlock Goji Rokakku

To get Goji first unlock noise tanks, love shockers, and poison jam, (get jet on EVERY SINGLE STORY MODE LEVEL) and beat the final stage of the game. When you load your game up after the credits the game you will begin a second quest (same as first, but none of your stage records, members, or graffiti souls will be deleted). If you unlocked the other 3 rival gangs (which you should have done to get goji, they will not be deleted). Goji is between Tab and Yo-Yo in the disguise of a blue oil drum, he has full power and graffiti but has low technique skill ( He takes a huge amount of damage when hit though ).

How To Get YoYo

To get yoyo you follow him to the group of buildings and skate up the ramp (TRUCK) jump through the orange billboard and follow the path. Skate up the street and turn right at the end of the road barriers and grind for 5 seconds max on the green rail then jump onto the path bellow. YoYo will go up the sections of stairs to trick you into getting lost but once you get to the end of the path you go straight across the road and you should then be able to see a tunnel go down through that and then you will be in the city and you turn left and go straight up. At the end of the buildings on your left there will be stairs go up them at the end grind down the spiral thing (THERE IS SPRAY CANS ON THE RAIL) at the end you jump straight ahead onto another rail thing and at the end of that you jump and land right in front of of the place you spray. WARNING this may take a few tries.

How to get Slate

Slate is a rival challenge, but he can be hard to get so, here's some advice. Grind as much as you can, it helps you go faster. Boost as much as you can, again, it helps you go faster. Ok, if you have YoYo its a lot easier too. HAVE FUN!
