Hawaii: Venice level bonus
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. 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.
Hawaii: Secret tape
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.
Hotter Than Hell: Secret tape
Get KISS once to unlock the video, then get it again to get the concert to start. When they are playing, use the doors on either side of the door that you can go through to the other side of the level. It will take you to the top of the level. You will see the secret tape in the air in front of you.
Hotter Than Hell: Freak show
Go behind the KISS stage to find a Freak Show stage. You will see things such as a human head, a man sticking swords down his mouth, a woman with a cinder block on her stomach, and a man with a sledge hammer.
Hotter Than Hell: 10,000 point gap
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.
Manhattan: Secret tape
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.
Manhattan: Hitch a ride
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.
Moscow: Secret tape
Go to the semicircle at St. Basil's (the building with a lot of spires), get off of your board, and walk up the ramp on the building. Next, jump and pull yourself up the wall. Get next to the center spire and double jump onto one of the corners. If done correctly, you will not slide down. Look up and you will see a bridge connecting the center spire to another spire. Double jump on the wall in front of you, move onto the bridge, and pull yourself up. The tape is on this walkway.
Moscow: Hanger level bonus
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. Stand in front of the AEHN building, then jump on top and go to the left-most edge of the building's roof. Grind it going towards the big red building. Jump through the window immediately in your view. Inside is a room where the secret tape is located.
Moscow: Straight Outta Moscow goal
When you get left behind in Russia, find Kalo (the man who asked you to blind the cameras). He will give you a bag and say that nobody can see you with it. This mission is frustrating because of the nightvision goggles you have to wear. There is a ladder near the pay phone where you start. Climb it and turn right to find another ladder. Climb it, but be careful as a guard will walk by. After he is away from you, get off your board. There is another guard standing. Turn the camera and enable the 'Moon gravity' cheat. Climb onto the ledge. Turn yourself so that you are straight with the statue in front of you. Jump once, then push yourself forward slightly. You should be on top of the statue. Jump over the guard and land back on the walkway. Walk all the way to the right and there will be another ladder (which will be flashing). Climb it then jump down into the quarterpipes. Walk out onto the castle. Look down and you will see Aleksander waiting. Jump down onto the ground and walk up to him.
New Jersey: School level bonus
In New Jersey, you can unlock the School level from Tony Hawk's Pro Skater 2. Cross the bridge, then get on top of the large building immediately afterwards. Shimmy across the tall gate and pull yourself onto a ledge. It will be on the ledge alongside a tall building. Have the station area unlocked. Go to the station area and get air off the middle quarter pipe in the back. You will see a floating icon marked 'Tony Hawk 2'. Run into it and the School 2 level from Tony Hawk's Pro Skater 2 will be unlocked.
New Jersey: Drive car
In story mode, after you complete the driving mission in Jersey, go up to the car to drive it.
New Jersey: Secret tape
Go under the bridge on the side that allows you to do so. The tape will be floating there for your taking.
New Jersey: Funny messages
Go to the station, then go down to the track area. Turn down the music all the way and listen to the intercom. You will hear messages such as, 'Please step back from the track. You may lose appendages', 'If you miss your train, tough luck', 'Tickets will be void if not real', and many other funny things.
San Diego: Secret tape
When you first enter the level, go straight ahead until you reach the street. Follow the street until you get to your first left hand turn. After this turn you will see a set of stairs at the end of the road. Go to the top of the stairs and look directly ahead. There is a concert-like building in front of you. On the left upper side of that building, you will see the secret tape. Use the quarterpipe on the lower level behind the building to get up there. Then, just jump up the quarterpipe to get the secret tape.
Slam City Jam: Secret tape
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. The secret tape is in the Jumbotron. You have to grind the rail that goes through it.
Slam City Jam: Tour title
On the big half-pipe on the railing, it will say 'Boom Boom Huck Jam', which is Tony Hawk's tour title.
Tampa: Secret tape
Go to the small building to the left of the cop car. Climb up the wire that is heading towards the tall building. The tape is in between the gap of the building at the top.
Tampa: Goat
There is a goat behind the strip club. Jump off your skateboard (L + R) and walk behind the strip club. There will be police and a goat there.
Tampa: Pole dancer
Go to the the strip club. Get off your skateboard and walk up the ramp on either side of the club. Grind on the ridges on the edges of the bubble on top of the strip club. This will cause the bubble to break. You can now get get to the top floor of the club. Inside the room are two businessmen and a stripper. There is also a little door in that same room. If you walk through it, you will exit out of the front door and the message 'Four hours and four-hundred dollars later' will appear.
Vancouver: Secret tape
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.
Switch tricks
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.
Alternate tricks using pressure
When you press L, you will switch into pressure, or switch pressure (depending on if you are skating switch or regular). Once in this stance, when you jump a trick will pop up called 'Pressure', and when you do a flip trick that is just Up, Down, Left, or Right, you will do a different trick from the usual pop shove-it, kickflip, heelflip, and impossible. You will be able to do toe flips (Left), 180 flips (Right), and FS and BS 360 flips (Up and Down).
Jump higher
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. You can only jump twice. Enable the 'Moon gravity' cheat and dismount your board. You can jump onto any building using the double jump method.
Moscow: Fatality! gap
Ollie into the snowman's head to knock it off. Blood and snow will squirt from where his head was located.
Hold on trick
Enable the 'Moon gravity' cheat and go to create-a-trick. For your first line, put in Front (or Back) flip. Then, switch it to 180 degrees. This will make your skater flip halfway. Set the duration between .4 and .7 seconds. On the next line, put an Other > Handstand. Have him hold it. This will make your skater flip halfway, get off his board, then hold on for dear life. This looks good if you get enough air.
Extra points
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.
Getting to hard to reach areas
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).
Easy competition wins
Enable the 'Perfect rail balance' cheat, then go on a quarter pipe and do a lip trick. If done correctlym your skater should stay in place until you press A. For first place, hold Trick until the point counter reads over 120,000 (about three minutes).
Easier game completion
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. You must have completed the game once beforehand to be able to skip it the next time.
Use any car used previously
After completing any goal that you had to use a car, you can find that car somewhere in that level as well.
Get skateboard back
If you have completed any of the vehicle goals for a level, and in the same level must do a goal without your skateboard, start the goal and jump into the vehicle. While still in the car (or other vehicle), restart the goal and you will have your skateboard back.
Scratched up deck
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.
Tony Hawk's Pro Skater 4 reference
In the FMV sequence at the beginning of story mode where Eric comes up to your window and tells you about Muska coming to Jersey, you can see a Tony Hawk Pro Skater 4 game box sitting on the desk when you slam the drawer closed.
Unlock All Videos
Go to the cheat code menu and type in "digivid" as a cheat code.
Big Combo's
Activate the perfect rail cheat(letitslide) in the cheats menu and then find a circular rail and just grind around it changing grind types contantly. This racks up big points because of the multiple tricks and the fact that you can grind forever.
Slow Motion
Once you've beaten all 129 goals you can activate the cheat called "cool specials" It allows you to do special tricks that take place in the air (eg. kickflip underflip, flamingo, McTwist etc.) go super slow. You need really high stats but what you do is find a long stright rail and grind it then jump do a kickflip underflip and start grinding right as your in the air. Then because it went into slow mo for the trick the grinding so soon keeps the slow mo until you do another special trick in the air.

The Forbidden Zone
(Note: You must have moongravity on for this cheat to work.) Go to the level Slam City Jam and get onto the stairs with the railling behind the glass. Go up the stairs to the arch with the letter on it. Jump to the top of the arch were the letter is and then jump against the letter in the air and onto the platform above. Now you can run or skate behind the seats. And for even more fun, go to the arches that are lined up side by side. Run up one arch then down again, run through the handrail at the bottem and keep on running straight into the seats. Now you can run or skate in the seats, but don't jump or run onto the stairs with a rail or you will have to do it again.
