Liberty City is dotted with 26 Unique Stunt Jumps, daring ramps and obstacles that, when successfully cleared, reward you with cash and contribute to your overall completion percentage. Finding and completing all of them requires keen observation and precise driving. Each island has its own set of jumps, often hidden in plain sight or requiring a specific approach.

How to Complete:
- Locate a Jump: Look for ramps, broken bridges, or specific terrain features that look like they could be used for a jump.
- Approach with Speed: Most jumps require significant speed to clear the gap or land correctly. Use a fast car or motorcycle.
- Land Successfully: You must land cleanly on all four wheels (or two for a motorcycle) without crashing or falling into water.
- Confirmation: A message will appear on screen confirming a 'Unique Stunt Jump Completed!'
Rewards:
- Cash: Each successful jump rewards you with a cash bonus.
- Completion Percentage: All 26 jumps contribute to your 100% game completion.
It's recommended to tackle these jumps after you've unlocked all three islands and have access to several fast vehicles. Some jumps are notoriously difficult and may require multiple attempts. Consult an in-game map or online resources for specific locations if you're struggling to find them all.
