While doing the "Wreck Yourself" goal on Capitol Hill in Career mode, run up to the red line coming from the left and moving to the right. Press TRIANGLE just after you cross the red line and steer your player to the right of the level. You must press TRIANGLE at the correct moment to get your player to go far enough. Aim for the white billboard to have a message appear, state that you are leaving the goal area. When time runs out, you will respawn on top of a shed moving back and forth. You can now spin any trick that you know. Nail the trick also works in this glitch. To exit, press L1 + R1 to get on your feet. Allow your foot timer run out to get all your points. If you are in the glitch and you missed a "nail the trick", the only way you can escape is to press Start and exit the goal.
There is a slope where you can manual down to get plenty of manual experience easily. The slope is a road that, when you look down it, you should see a building with a "COME AGAIN!" sign on it. There is a spot challenge at the start of the slope. If you start it, you can manual all the way down. Don't worry about hitting all the spots or anything else. To earn easy experience, just go down the hill as far as possible. When you get to the bottom, instead of going up, just restart your last goal. You will be on the spot challenge again at the top of the hill. Repeat as desired.
In the training area pick Dustin Dollin and complete his first lesson. Press L1+L2+R1+R2 to Force Bail and when he gets up press L3 + X. The game will re-load with Dustin Dollin at your crash pad. Go to Edit Skater and change his head. His head, legs and hands will be removed.
Find an editor goal where you can move kickers, rails etc. around. Crash into a local skater or pedestrian to get them to chase you. While you are being chased, skate to the editor goal and start it. The pededstrian will run into you off screen. You will now be looking down upon your skater from above, and can still move pieces around.
If there is a spot challenge nearby, you can start it in the bird's eye view to revert the camera back to its normal position behind the skater. You can still move pieces around, but if you do a grab trick the editor goal will end.
Stall on a car that is moving and skitch it through town. Jump off when you are about to fall. You will get a lot of Stokens.
Start at the entrance where the cars first enter. When the cars come through, hold Up until you are skitching. Ride on that car until it goes around the city and starts to get near the entrance again. Jump off before you get to close to the entrance. Do not go through the entrance or you will not get the Stokens.
Go up to a guard while off your skateboard and jump a couple times over him. Occasionally you will get an extra boost in air. Do this to jump up to a place that you cannot normally jump high enough up to. Hit a guard and make him chase you to the slums. In the lot in front of the Jeep Factory is a hidden spot icon--hop the guard and collect it.
Play the first part of Bob B's Pro Challenge. When you are falling through the air, it counts towards your air stats. Begin the mission and start flying through the air.Let the game idle like this since it repeatedly resets the mission and when you do not perform all of the tricks and hit the ground, it just puts you straight to the top and never stops.
