How to do '; Nail 2 trucks up Branches'; on tony hawk's proving ground for ps3?

a truck up branch is when you do a trick (in NTT of course) while the trucks are up. (the trucks are the metal parts that holds the wheels. In other words, just when the wheels are up)





so, get into nail-the-trick and do a trick, like a kickflip or an imposible, and when the board is upside down (trucks up) do another trick, any trick, and then, repeat after than trick the same, another, any trick, while the board is upside down. Once you get those truck-ups tricks, do a final trick to get the board normal again (wheels down) and release the sticks and catch the board
