Stunt Jumps in GTA Chinatown Wars

Unique Stunt Jumps (abbreviated in game as USJs) are a collectible in Grand Theft Auto: Chinatown Wars.

Each Unique Stunt Jump in Grand Theft Auto: Chinatown Wars requires the player to destroy one of 30 wooden Rusty Brown's Ring Donuts billboards with a vehicle. If a previously destroyed billboard is revisited, it is shown as shoddily-repaired, which indicates that this jumps was already completed.

There is no reward for completing the stunt jumps aside from 100% Completion.
