"Pull as many unique trick combinations as you can when in the air. It keeps the adrenaline high so you can sprint longer when not jumping. Keep tricks unique. Every time you pull the same trick, it's worth fewer points. Super-Style your tricks. Pull a trick and hold it, then press triangle. If you can super-style more than one trick in a jump the points really climb. (I once scored over 7,000 points in one jump.)" - venatical

"If you really want to get a huge score, just hold the brake and do a stoppie for as long as you want. You will finish last, but you get a big fucking score. This also helps in freestyle mode when you have to score a certain amount of points. Also, if you want to earn points the honest way, do tricks while doing a quick flip or quick spin. (I once landed a 30,000 point trick)" - EVAN

"Real quick, you can unlock everything without even beating anything. Just pause the game then hold R1+R2, press x, circle, x, release R1+R2, then really fast press x,o,x,o,R2,L2,triangle. That's all there is too it. Race on!!" - mxdude87
