This is a glitch that i found because i was bored..... and well it can get you more than 100mil points,train your charecters spin, or air, or whatnot but it can only be done on one level. Go to downtown baltimore and then skate your way up to the fountain. Get off your board and try to aim your sk8er a little bit behind one of the jets but where your feet are about to touch the jet.Get back on your board now. Do a PERFECTY strait jump by jumping and then holding backwards.If your charecter continuslly gets hit by the jet then your doing the trick right, but there is a few steps that must be followed carfully or else this has been a waste and youll get a NEGITIVE score.
Now: keep doing front-flips by holding up on the d-pad and on the analog, and wait for your score to get close to 10,000,000 (which might sound long,but really only takes 15-20 seconds) and then do a bunch of kickflips to add to the multiplier. BE VERY CARFUL NOT TO GET THE POINT TOTAL OVER 10,000,000 POINTS WHILE DOING THE FRONTFLIPS.... THIS WILL MAKE YOUR SCORE HAVE A NEGITIVE NUMERAL IN IT, WHICH DOSN'T HELP AT ALL.To get off hold up on the analog and continusly press the A button. When you land youll make an unimaginable high-score.
to train an air stat: just simply do what you would do to level the stat. EX: train spins, just spin one way, to train air, simply stay in the air.
