Glitches

Climb Up Walls

This glitch is quite simple. First enter the Moon Gravity code. Then run up to a building on foot. Jump towards the wall. Hold in the direction of the wall and keep hitting the jump button. If done correctly, you can keep jumping up and get to places you normally couldn't go. There also some bizarre areas not usually accessable either.

Infinite Spin

In any of the Hangar Old School level, turn Moon Gravity ON, and go to any of the 4 corners of the level. Then, ollie up one of the vert ramps into the ceiling corner and you should stay there and never come down. While up there, you can do as many specials, tricks, spins you want. I have done many 900s in a row and got my spin up to over 50,000 before I got bored. The only way down is to press R1 and L1 to get off your board.

Inside barriered places

Go up to a wall with Moon gravity on and be in stand mode. Constantly keep jumping and jumping into the edge of the map until you jump over the barrier. Then you can walk around inside houses or other neat places

Lip Trick Any Rail

Air off a quarter pipe with a rail or other lip above it. Lip the rail/lip with a trick you can jump up from, such as a noseblunt, and jump up from it. Before you hit the ground, press L1 and R1 to get off your board, then quickly hit R1 again to grab on to the object you just lipped. Press down and wait for the run meter to run out. Walk around to the rail you want to lip. Caveman grind any rail you want, then ollie to another rail and grind it. You will proceed to do a lip trick on the second rail when you should be grinding. This is not limited to rails-you can do it on any grindable object.

Past the Level Boundary - NJ

In New Jersey, get in the car and back it up past the corner just to the left and bottom of the screen(where it starts you over again for going past the boundary) and keep going in reverse as you get placed back on the screen with the red letters, after it says whatever(while still holding down reverse) you should go past that boundary in reverse and your car will go so far before melting into the the ground half way and glitching out madly.

Past the Level Boundary - Slam City Jam

Right after the level starts, turn right and go towards Exit C. Get off your board, and stand stand at the corner (to the right of the sign saying ''To Concourse Level'', and jump up, grabbing the rail. Move as far left as you can, and climb up. You'll fall down beside the chairs. Staying as far left as you can against the glass without touching the chairs, walk forward untill you reach the stairs, then go up them untill you reach the top. At this point, you can run around through the chairs and everything else. However, you can go ever further out of the level. Run up any of the flat stairs to the blue seats, and run untill you reach the section under the red VANS sign (if you walk on the seats below, you'll die). Go up to the stairs, face the flat stairs heading up between the blue seats, and jump into it. You will fall through, land at the entrence, and will be able to walk outside of the building as far as the road, to be able to look at the flat vehicles. If you follow the road to the left or right, you can even walk through the doors of the building across the street, which is the Vancouver Hotel.

Perfect Manual Without Using Cheat Codes

If you manual towards a wall (best to manual towards it slowly) and land it just before you hit the wall (i.e. Press the Up directional button) and time it just right, you will bounce off the wall and be still in your manual, except the balance meter is frozen, so you can do as many pivots as you like,. However, as soon as you jump you manual will be back to normal again.

Spine Transfer Glitch

Create a board and put two house boats made exactly the same and in the same direction so you can spine transfer over one little hut onto the plain quarter pipe. If you start on the plain side and spine transfer just as you pass by the little over hang, your character will stiffen and melt into and under the little overhang letting you do up to 11-16 tricks(best to do grabs) for massive amounts of points and to land it, simply jump off the board by pressing L1 + R1 then either let the timer run or throw in a few more tricks.

Stand-Off-Your-Board-While-Tricking Glitch

Go to New Jersey in Career Mode and begin grinding a looping rail (such as the train tracks), lip-tricking, or manualing. While doing this trick, pause the game, go to Options, then Watch Cutscenes. Select Muska Demo and skip through the two cutscenes, if you wish. Once the preview is over, return to the game to see your skater in a stand off the board posture. However, the trick will continue so the skater stands while grinding, lip-tricking, or manualing.

Use Pro's in Story Mode Mission glitch

After you pick your team of 5 pro's, attempt the Vancouver Spine Challenge. Pick any of your pro's, and begin. Do the first part of the challenge, which are the three spines. After that, the game tells you to do a big combo, and if you dont git it right the first time, you fail. So, after doing the spines, intentionally bail, and the game will make that annoying screeching noise, the game will pause for a second, and restart you with your guy. Well, IMMEDIATLY after the game is bout to show your character, after the failure, press pause. If you did it right, your guy should be kind of crooked in the background. Now, pick Retry Last Goal and the game, if you did it right, should make that annoying screech sound again. After that sound, it will ask who you wish to skate with. Pick any of the pro's, but instead of the game loading up the mission again, it will just restart you again as if you failed the mission, but you will still be skating as that pro. Feel free to change levels, and do goals that you have yet to finish. You'll still have all of your C.A.S stats, and you'll still talk like him, but you'll be one of the pro's.
