Hints:-

Airport level: Baggage check:-  Immediately when you start the level, go to the right and ollie into the place where you usually check your bags to get on an airplane. It will lead you to a location with a helicopter. To leave, either go backwards or down the staircase. 

Airport level: Go inside baggage claim:-  Jump into the hole with the conveyer belt and you will go inside. 

Airport level: Extra points:-  Use the following steps for an easy way to get over a million points in a trick. Skate down to the baggage claim area. From there, go to the left side and grind up the far left escalator rail. Let yourself grind up and slide back down. Once you slide back down, jump to the next rail and so on. If done properly, the rails form a continuous loop as long as you can stay balanced. Special grinds help a lot. 

At the start of the level there are the two little walkways. When you jump from one walkway bar to another while grinding you will get huge points. Do this four or five times before the walkway ends and you may get 50,000 easy points. If you manual to the next walkway and continue the same thing you can get at least 150,000 points. 

Airport level: Secret tape:-  Turn up on the screen once, go across the quarterpipe and ride the rail. Immediately jump up on the white rail in the air and ride it until you get the secret tape. Once you obtain it, do a 50/50 grind to get down. 

Enable the "Moon physics" cheat and go to the place where the last pick-pocket is located. Run him down, go up the quarterpipe and ollie up onto the highest rail. Do any type of grind to get the 411VM tape. 

Canada level: Hidden path:-  When you are going up to the broken railroad tracks (where you would find the secret tape) instead of turning right; go left. You will follow the track and then some electrical wires and end up at the beginning. 

Canada level: Hidden message:-  Skate to the woods in between the broken bridge and the plank leading to the halfpipe. Immediately before the start of the plank (looking at it), look to the left at the snow. There are letters in yellow that say "Neversoft rules!" in the snow. You 
have to look carefully, because it blends in with the snow. 

Canada level: Urinating man:-  Go towards the halfpipe that is raise-able. The man is located at the quarterpipe next to it. He is standing on the left side. 

If you run into the urinating man, he will fall off the edge and go into the lake screaming. You will not see him again until you quit or retry the level. 

Canada level: Bury The Bully comment:-  After you Bury The Bully, stand next to him. You will notice that two people are throwing snowballs at him while he is buried. Eventually the bully will say "Hey, that snowball was yellow!". 

Cruise Ship level: Cake:-  If you find the cake somewhere on the Cruise Ship, hit it and watch a different cake appear from the bottom. There are three cakes in total. 

Cruise Ship level: Extra points:-  Enable the "Perfect rail" and "Super stats" cheats. Go to the pool and get lots of speed. Start grinding the outside of the pool. Since there are a lot of women around that area, they will keep giving you prop thus enhancing your score. Since you have a lot of speed you will go over the gap where the water slide is located and also increase your score. You can do this as long as desired. 

Catch air off the quarterpipe where you started and grind the high wire. Keep grinding over the red top of the boat until you get to the lights on the edge. You will go around, come up an incline, and slide back down. Keep grinding. Enable the "Perfect balance" cheat to make this easier. It is possible to get up to 20 million points. 

Cruise Ship level: Alternate announcements:-  Break all the glass in the greenhouse as any character. 

Cruise Ship level: Wall ride:-  Go to the area where you can ride on the safety nets. You must unlock the propeller in the museum first. Ride up the red ramp slowly. You need to be near the place where you grind on the net. Turn around from looking at the grinding for the net spot 
and go up the red side of the ship. You will fall off after a few seconds. 

Cruise Ship level: Super death:-  Enter the room where you can do the Complete Bob and launch off of the side of the quarterpipes. If you land the correct way, you will sit down next to a pole on top of a small ramp and start bleeding profusely from the back of your neck. 

Cruise Ship level: Real captain:-  Enable the "Moon Physics" cheat and smash every piece of glass in the greenhouse. You may have to drop from the pool deck through the greenhouse. Once the last piece has smashed, you will hear a fight followed by someone screaming as if he was thrown off something very high. This is the fake captain going over the ship. Then a new voice will say that he is the real captain and the man that you were listening to was a fake. This new captain will say the same things as the fake, but in a different style. If you do not hear a new voice, smash every piece of glass you see, including the shops and the museum. 

Cruise Ship level: S.O.S message:-  Once you have unlocked the real cruise ship captain, skate around. You will eventually hear a bing-bong to say the microphone is on, then a Morse code message that reads "S.O.S" twice. 

Foundry level: Secret tape:-  To get to the secret tape quicker, enable the "Moon physics" cheat. Ride and ollie over Funbox under the molten bucket. Once there, you should be up the secret floor. Ollie off the fly-off ramp and quickly grind the metal bar with the 411VM tape on it. 

Foundry level: Man getting treated:-  To see a man getting treated, go to the far end of the foundry to the windows. Then, go to the last but one window on the left. You will see a doctor talking to a man who is sitting an exam table. 

Foundry: Neversoft juice:-  Enter the foundry level and go to the top end of the building where the molten bucket is located. Go to the window on the right and you should see a man getting a drink from a Neversoft juice drink machine. 

Los Angeles level: Earthquake:-  To cause an earthquake in the Los Angeles level, and complete two of the required objectives (cause an earthquake and block the car chase), grind the four tremor rails (North, South, West, and East). All of these rails are on the far sides of the levels and look metallic brown. One is near where you start, another is in front of the movie theater, and the other two are near the bridge and the park (where the purple half-pipe and the pink balls are located). After you cause the earthquake, get up on the bridge by catching air off the "halfpipe" near the liquor shop and landing on it. Grind on the green car to make it stop the car chase. 

Los Angeles: Hidden halfpipe:-  Go back in the right corner of the level, behind the car wash where the photographer takes your picture. Look for the round corner. You will see two grates on the ground. Grind on the round corner starting at one end all the way to the other. Note: If you have to jump, then you are grinding the wrong location -- you will grind all the way around the corner. After you grind this, if done correctly, you will hear the sound of the grates falling. You will have unlocked two new half pipes. There is one that is directly in front of you and another where the gates are on top of that building where you get onto to get on the bridge. Also, for some skaters this will get easy access to another stat point. 

Rio level: Change park layout:-  When first starting the level, go to the right side of the park. There is a platform immediately after the humps. It is supported by some wooden stands. One of the stands looks very shaky. Skate into that and you will knock the platform down. 

Rio level: Hidden area:-  There is a wooden fence going around parts of the level. On one side of this fence is a section with boards nailed across it. Ride into these boards to reveal a secret area with a pool and some grinds. 

Rio level: Gold medal:-  Enable the "Moon physics" and "Perfect rail balance" cheats. Ollie up onto the middle telephone wire and grind by 50-50, then turn it into a Nosegrind and last there until you get a large amount of points. Then, Ollie off and do it again in the other runs. 

Skater Island level: Pirate ship  -  Grind the pirate flag between the half-pipe and the set of bowls to open up the outside level (where the last stat point is located), and gain access to the pirate ship. 

Skater Island level: Parrot and captain speeches:-  Once the pirate ship is unlocked, go to the ramp. Go up it and turn right. Get air from  the first quarter-pipe (the lower one) then head towards the middle of the quarter-pipe at the front by aiming slightly to the left of it. Perform a lip trick on the higher ledge and you will see and hear a parrot and the captain talking. Each time you do it, the speeches will be different. The Parrot says something like "I'm the best, you suck. I'm the best, you suck" and the captain talks about life at sea. 

Skater Island level: Ship fight:-  Once the Pirate ship is unlocked, you will see two quarter-pipes that have cannons mounted on the top. Lip trick them and the cannons will fire at the ship 

Skater Island level: See Cruise ship:-  Head onto the pirate ship and go to the other side to see the Cruise ship. 

Suburbia level: Thin man and videotape:-  When helping the thin man, you may notice that his keys are not easy to find. That us because there are no keys. Instead, he can use the ax that is in the construction yard. Go to where the men are building a house. There are some boards set up to be cut. The one closest to the road has an ax in it. Grind this board to pick up the ax, then return to the thin man. After you have done this, you will be able to get the videotape. 

Suburbia level: Hidden tape:-  Enable the "Moon physics" cheat and go to the haunted house. Get as close as possible to the steps outside the door that opens and closes. Ollie up on to the porch thing. You will see a metal bar with the tape on it. Ollie onto the bar and grind on it.  You should now have the secret 411VM tape. This method saves a lot of time. 

Suburbia level: Haunted house halfpipes:-  Once through to the back, use the ramp you land on to get air off the ramp ahead to get onto a halfpipe above the house. Use the same technique used in Canada. Look further to see where you can get onto the roof. You can jump over the edge to return instead of going down and through the normal exit. 

Suburbia level: Zombie hands:-  After opening the haunted house, go through to the back and skate towards the gravestones. Jump behind them and zombie hands will appear. 

Suburbia level: Demoness' home:-  Go through the evil door as Demoness. You will hear the scream, but it now says "Welcome home" and the thin man has hearts all around him. 

Suburbia level: Scary face:-  Find the ax and give it to the thin man. Then, go in the house, get into the open space with the walls of quarter pipes and you will see a quarter pipe with a slanted wall on it. Ride up that quarter pipe while holding Up. You will be in a room with a man  scared because of a floating casket. Go past him and out the window to where the hidden tape is located. Once you land on the ground, look into the house door there will be a scary face. If your timing is good and you manage to jump into the door, you will die. 

Suburbia level: Extra hot grill:-  Play as Demoness and hop the fence directly off of where you start from. There will be two men attempting to barbecue. Ollie over their grill, the gap name "Hot Foot" will appear. Look to see the grill flaming very high. 

Suburbia level: Squirrel Stew:-  From the start of the level, head over the ramps then over the fence where the two men are near the BBQ. Turn to face the quarterpipe at the back of the house on the left and ride towards the ramp leading to the roof. Once at the top, turn around and  you will see two wires. The lower wire is the one you need. If you are lucky, a small black blob can be seen on the wire. When you grind over it you will squish a squirrel and get a "Squirrel Stew" message appearing with whatever tricks you have done. 

Suburbia level: Gassy man:-  Go to the area where the two men are building the house. If you stand close to the one in the red shirt, he will fart, You have to stand there for a minute or two to hear him. 

Suburbia level: The thin man's half-pipe:-  There is a half pipe on top of the mansion in Suburbia. The easiest way to get there is to go through the door you helped the thin man create. Jump over the wall as you normally would to get the "I Got A Bad Feeling About This!" gap. As soon as you make it over, go straight at the house, You have to be very close to the wall you just jumped. Jump to the right and onto the house. You will get a gap called "Look Out Behind You!" Turn around so that you are facing the house again, then press Up to make the next jump. The half-pipe is there. 

Suburbia level: Plane drop:-  Go to the quarterpipe with the table on it. Launch off the pipe to the plane that passes by.. If you get on the tail, you will drop from above the picnic table for a 20,000 point gap called "Plane Drop". 

Suburbia level: Utopia mystery:-  As soon as you start, look to the left for a sign with an arrow on the top. It reads "UTOPIA" and the arrow is pointing to the right. If you go in that direction you will see an airplane taking off. It only takes off when you get relatively close to the motor homes. If you skate into the sign, the letters "U," "O," and "A," fall off. This may be the beginning of a secret area or just an action normally done in the game. 

Tokyo level: Hidden area:-  Go to where the spectators are sitting and grind the top of it to get on to the wire connected to the commentator's booth. Grind to the building with the half circle sign (next to the building with the large circular sign). Grind to the building with the circular sign to find a small halfpipe. Jump into the big sign to enter the hidden area.

Tokyo level: Ride the buildings:-  Enable the "Moon physics" cheat. Facing the way you do on a normal start, on the far end of the left side wall is a sign you can break through. Grind the train rail to get through the sign easier. In the sign is a hidden half-pipe. Go up and do your best trick, jumping in the direction opposite of the side you broke through. When the "Slow motion" cheat is also enabled, this will give you the biggest tricks in the game. 

Knock people down:-  You knock people down by simply skating into them. This can help in Canada, with the task, "Get Chuck Unstuck". 

Burn Skate Shop clerk:-  Go to skater selection screen and scroll to Demoness. The skate shop clerk will start to burn up in the background. Move to a different character and he will get back up, alive again. 

Choke Skate Shop clerk:-  When scrolling through the characters, go to Darth Maul. The clerk will float up in the air and start choking. 

Ollie The Bum: Whiskey bottle:-  While playing as Ollie The Bum, turn switch and do his special (Panhandling). While switch, instead of holding his sign he will hold out his whiskey bottle. 

Rodney Mullen: Hand-360 Flip:-  Give your character the "Handstand to 360 Hand Flip" special. When performing this move in a run, enter the controls and then ollie straight away. If performed correctly, your skater will reach down, grab the board, then flip it like in Rodney Mullen's video.

Choking pedestrians:-  Unlock Darth Maul as a skater. Do a free skate and go to Los Angeles, Airport, or anywhere else where there are pedestrians that say "Hey!" or "Watch Out!" as you skate by them. Skate slowly near them, and as soon as they scream at you, turn and face them. They will float up in the air and start choking until you look away. 
Note: This trick will not work on the pedestrians that fall or hit you when you go near them. 

Extra trick slots:-  Successfully complete all nine goals in any regular level to unlock an extra trick slot. 

Recover faster:-  Rapidly press Up after bailing. 

Panhandling: Sign:-  When doing Panhandling as Ollie the Bum, he holds up a sign that says "Will skate for food". 

Extra points:-  Go to any level that has long rails. Start a grind, Ollie, do a flip trick, then grind again with a different grind than the one done before. Keep repeating the process for up to 300,000 points. 

UFO:-  In Tony Hawk's video, there is a UFO at the very end where he does the 900. 

Pedestrian actions:-  There are three types of pedestrians. The first type will fall down instantly when run into (for example, the welder in the foundry by TC's rail). The second type will try to jump out the way. If you try to hit them enough, they will knock you down (for example, :the teens by the trailer park n Suburbia). The third type will take you down instantly (for example, the girls on the Cruise Ship). As the Demoness, go to almost any level (except the Cruise Ship) with pedestrians. Try to hit the second type of pedestrian, then turn so that she is facing them. After they jump out of the way, the pedestrian will shrink. 

Get the Demoness, then go up to any person in the game. Get very close to the person without tripping him/her, making them her jump out of the way. Once done, stare at the person face-to-face and he/she will shrink. 

When playing as Darth Maul the second type of pedestrian will choke themselves while walking on air. With Private Carrera, they will dance and say strange things. When playing as Wolverine, they will get into a boxing stance. When playing as Officer Dick, they will hide in terror. 

Eric Koston's FMV sequence:-  In Eric Koston's FMV sequence, when he is putting away his laptop computer in the restaurant from playing Tony Hawk's Pro Skater 2, you can see Rick McCrank picking his nose. 

Geoff Rowley: FMV sequence:-  In Geoff Rowley's FMV sequence, look in the background for the entire time. At one point, a guy in the background will stick his arm up his shirt. 

Rodney Mullen FMV sequence:-  When Rodney Mullen is doing the truckstand, the girls in the seats in the background are aliens.
