In other jumps, too much speed may lead you to overshoot the landing area. Some jumps require high speed, thus are only feasible on a fast motorbike such as a PCJ-600 or NRG-500, and sometimes also require the character to lean forward on the bike for increased speed. Upon landing, indication of success is given, while an unsuccessful jump will receive no message. If your vehicle hits the takeoff area in more-or-less the right direction, the game switches to a slow-motion cut-scene panoramic view as your vehicle launches from the takeoff area. Each unique jump has pre-defined takeoff and landing areas miss either, and the jump is incomplete. The game tracks these for your stats, and completing all is usually required for 100% completion. A Stunt Jump usually involves using a vehicle or motorcycle to jump of a ramp of some sort (sometimes an actual ramp, or something similar to a ramp like a slanted roof or staircase), then to catch a few seconds of airtime, then land on the ground without dying.
Unique Stunt Jumps (named Unique Jumps in the GTA III Era later renamed Stunt Jumps in Grand Theft Auto IV) are a feature in every Grand Theft Auto game since Grand Theft Auto III (with the exception of Grand Theft Auto Advance).
