Marvel's Spider-Man 2
Hang Ten Trophy in Marvel's Spider-Man 2
Perform 30 Air Tricks in a row without touching the ground
In the air, hold and push L stick in any direction for a trick. Each trick shows its XP at the right of the screen. Swing with R2 between tricks to stay up. Touching anything ends the run, and that includes running into a building's wall.
Watch out
Keep going past 30: it can take around 40 before it unlocks.
