I've found a little trick/glitch in the game on the Slam City Jam level. All you have to do is simply grind across DJ Q-berts table. Not only will you score the "Ho Brah, Dass Dj Q-bert" Gap, The song thats currently playing will change. This usually works the first time you grind the table, but somtimes it takes a few grinds to work. **Note** This trick also works with custom soundtracks
I've found a "glitch" in the game that allows for really neat looking slow motion skating. First off, you need to have the "Cool specials" cheat activated. Now, go to the Edit Special tricks menu and assign your skater a trick like the 900 or Back spin air. When you've done this, go back to the game and skate towards a rail or ledge. Start to do the speical trick and then land in a grind before the trick is completed. You will be stuck in a sweet looking slow motion mode. If You pause then unpause the game, the hazy/blurry effect will go away but you'll still be in slow- mo. To return the game to normal speed, LAND a speical trick like a Kickflip underflip or flamingo in a halfpipe or off a ramp. **NOTE** This trick will only work on the "Too Easy" Difficulty.

In Hawaii, you can unlock the Venice level from Tony Hawk's Pro Skater 2. From the large hotel you start at, follow the main road all the way around in either direction. When you find the strip of buildings that are opposite on the map from the hotel, you will find a large tiki head. Alternately, go out the front doors of the hotel and through the plaza all the way out the other side. Jump inside the tiki head's mouth to find a secret area. Skate down the tunnel until the end and boneless into the air to grab the unlock for the Venice level. Note: Think of the map as a square. If the beach is at the bottom, the tiki head is on the top side of the map. It is much easier to get inside the tiki head's mouth if you dismount your board first.
Climb the hotel that you start at. Get to the roof and to the right of the pipe on the right is the side of the building. Grind that ledge onto the wire to get the secret tape.
Find the Go-Kart. Drive the Go-Kart around until you find a huge ramp that goes over the center of the level. Drive off it as fast as possible and you will clear a gap that gives you 10,000 points.
When you start, go down the street to the left of the worker with the jackhammer . At the end of the street is a lit up billboard with a ladder. Climb the ladder, then jump and grab the ledge. The tape is there for the taking.
When skating in Manhattan, it is possible to ride in the back of the DC trucks driving around the city. Skate behind one and jump into the back when you get a chance. Doing so will allow you hitch a ride around the block.
Find the place where there are a lot of tanks and a building that reads "AEHNH". Stand in front of the building to the left. Line your self with the brown ledge. Climb up it. Stand on the brown ledge that you are about to grind on. If you are in the correct location, to your left should be a tree and straight ahead should be a big red building palace-looking thing. Grind that ledge and jump toward the previous viewed window. You should go down a ramp. Where the ramp is located, is a ramp that goes up on the right, revealing the secret level as you went down the ramp.
In story mode, after you complete the driving mission in Jersey, go up to the car to drive it.
Go to the vert ramp and get off your board. Climb up onto the lights hanging from the ceiling and walk over to the big four-sided television screen. Walk into it and the glass should break. The secret tape will be inside.
Start at the entrance of the stadium (where the parked trucks are located, and where you get into the contest. From there, look at the tape. You should see it above the glass dome behind the subway-like spline entrance. Go down left from here and wait for a vehicle to drive out of the tunnel. Skitch it towards where you started from. Make sure you are on the left side of the car. When you are about to pass the subway entrance spline, get of the vehicle and spline the entrance from the side. This will launch you across the dome into the secret tape.
Riding switch is the opposite of what your rider is used to. If you have a regular stance rider, then switch would be the goofy stance for them, and vice versa. When you do switch tricks, you get more points than what you would normally get for doing it in regular/goofy form. For example, doing a Kickflip (regular) results in 100 points, but a Switch Kickflip gets 120 points. It makes a larger difference on bigger tricks such as specials.
While off your skateboard (walking), when you jump the first time, you can also jump a second time while still in the air (if you keep tapping Jump). This is very helpful for out of reach places. Note: You can only jump twice.
Do a trick off a vert ramp. Then, jump off your board. While the timer is still going, do tricks on your feet for extra points.
During any time that you can set a restart from the options menu (in game), you can use it to get to areas otherwise impossible to reach. Ollie then pause game play before you start coming down. Set a restart while in the air. Then, go to the restart, quickly Ollie again, then set the restart at the top of the Ollie again. By repeating this you will get higher and higher, and may be able to access rooftops and ledges (if you are close enough).
If you are stuck on the final mission, all you have to do is complete a total of 96 missions to finish the game. In order to unlock the bonuses, backtrack to an incomplete goal (for example, the first chapter), and you will see the videos. This works especially well if you are completing sick mode, considering the final challenge has a considerably shorter period of time to finish.
After completing any goal that you had to use a car, you can find that car somewhere in that level as well.
Create your own deck or get any pre-made one. Grind a lot with it by doing tailslides, noseslides, boardslides, and lipslides. After grinding for so long, your board will wear on the bottom and the picture will be all scratched up.
Go to the spot where the skate demo is held. Get to the top of the bilding and on the right side on the small half pipe is the tape.
There is a big building that says Metrocenter on it, and there is a sign in front of it that says welcome, just clime up the ladder and the tape is up on it.
Ok this one is kind of hard. Theres a building that says D'amoto on it, go up the ramp on the side of it, get on the roof and acid drop on the ramp. The building in front of it has a quarter pipe, go up it towards the middle of the gap, when you hit the peak, caveman and jump. It might take a couple of trys but you will get it.
After you unlock the train station, you nead to get inside and down to the track, go up the half pipe on the north end and it will be at the top.
First you have to jump the bridge to unlock the train station. Once this is done go under the bridge and its right there.
Find every gap in the game and you will be able to play as over 2 dozen pedestrians found in the game.
Complete story mode on the Sick difficulty setting.
Complete story mode on any difficulty setting.
Complete story mode on either the Normal or Sick difficulty.
