There are 50 stunt jumps that the player must complete in order to get 100% completion in Grand Theft Auto IV. 4 possibilities after a jump (the second two possibilities represent a welcome improvement from 3D Universe games): * If the player is successful, the game will report "Stunt jump completed" then "XX stunt jumps left to do." * If the player is unsuccessful, the game will report "Not good enough." * Unsuccessful, already completed: "Not Good enough, but you have already completed this stunt jump" * Successful, already completed: "Stunt jump completed again"
