Freeze Way 1: Canada: Go to the QP half where you go to get the THPS3 secret tape. See the kid at the edge of it? Lip on him. He'll fall off. BUT WAIT! Now go to the corner about 2 feet back to the right. Get on it and follow the edge. Lip again. Once you get stuck, change the level to Training. It should load 1/8 of the % it takes. Once that's over, you'll float in a snowy barren wasteland for 5 seconds. LOL.
Freeze Way 2: (Make sure the earthquake hasn't happened, right when you start the level suggested) LA: Manual the right stair barrer. (It's white) [The very right one] If done corrrectly, it should say: Manualed down (something, I forget) 1 time! =/ Now, go to the Earthquake rail sraight ahead a little left. Grind it and jump off right.. Should say, "Northern Quake Rail!" Now continue right until parallel with street. Then, EARTHQUAKE!!!!!!!!!! LOL Oh, game froze. =)...=/...=(...
NEW DISCOVERED FLOAT GLITCH!!!!! Go to the training level. Go down all the way. Go to the corner on the right. Keep doing flip tricks in that corner until you get stuck. HOLD TRICK LONG. Once your multiplier goes to 11, it'll stop, so hold that trick until it stops. Get off your board to exit this. Link huge combo's and score big points!
