Amped: Freestyle Snowboarding is the first snowboarding game focused on freestyle riding. Rip the ultimate line on wide-open real mountains packed with jumps and rails. Hit the cliffs, jib the rainbow tree trail or take the hidden path through the trees for a different ride every time. Pull insane tricks in front of roaming camera crews to get your face on video and magazine covers. Get enough international exposure to become one of the world's snowboarding media superstars. And do it all to the music of over 150 core indie tracks
