Project Gotham Racing 2

Go to the garage and press Y to walk around. Go to the arcade machine to left of the garage door (where the wheels and filing cabinets are). Press A to play the arcade game. The game is called "Geometry Wars". Here are the controls for the game:

Move: Left Analog Stick
Shoot: Right Analog Stick
Bomb: R

Select the Porsche 959 with a manual transmission. Get the car up to top RPMs in first gear. Turn hard to the left and throw it into reverse. As soon as it is in reverse, accelerate in reverse quickly. Hold the accelerator and the car should spin wildly. This takes several tries to get it to work at its best, but you can get the car to spin like a tornado forever if done properly.

On any track in online xbox live play you can drive backwards, but it takes 2 laps for every actual lap. so 3 laps is really six laps. all you have to do is drive over the start line and do a U-turn. and go go go. Whoever crosses the finish line 1st, aka 6th place is 1st on the leaderboard and gets the bonus kudos as well.

Enter multi-player mode and select the Nurburgring track while it is raining. Race in a Yellow Ferrari F40 and a Yellow Ferrari 250 GTO. You will start on a large straight away. From there, have the Ferrari F40 will turn around and go the wrong way while the Ferrari 250 GTO drives the correct way. Once at opposite ends, turn around a race down the straight away at each other and collide. You will need to get a lot of speed. Once you collide with each other one of the cars will hopefully be hurled into the air. This may not work the first time, keep trying until it does.

Play the St. Basil's track and race down around the hairpin turn and up to the drop followed by the hard right. Have one car turn around and face the opposite direction around the track then back up and drive forward to stay solid. If you do not do this, your car will be invisible and this glitch will not work. Have other cars one at a time start at the end of the hairpin and go down the straight, headed for the other car. The car on the drop will need to time this perfectly to drive up the hill some distance to hit underneath your car and send you flying. Once airborne, turn hard to the right so that when you hit you will spin out. Pull donuts and slides all over the other straight to get huge combos.

Go into Extreme Series and select either the KZ 1 or the F-40. Race at Washington D.C. up and over the novice setting. When the race begins, stay in last, go down to turn one, and do a 180. Back your car up to the wall and wait until the other cars come around the track on the map about halfway through the straight coming to last turn at the top of hill before start/finish line. Accelerate, and if timed correctly you can hit a car head on towards the top of the hill. You will go up into the air to the limits of the game, which is over the tops of the buildings. This works with both cars. If you finish the race you can save the glitch on replay.

This glitch only works on the Porsche 959 (Extreme Class). You have to be in MANUAL for this to work properly. When you get into the race, (KGB is a good track to use for this) start moving in first gear. Drive until first gear maxes out (about 42 mph) then make a hard turn left, let off the gas for a second and press the ''downshift button'' (The default for this is 'X') which will put it in reverse. When you begin spinning, press and hold down the gas again and you should spin extremely fast.

When you are at the car series select screen, press the following buttons: X(4),Y(4),X,Y,X, then press Start.
