Extreme-G is a futuristic racing game with an emphasis on speed. It also features many weapons and an F-Zero style energy shield and regeneration. You are able to break the sound barrier where you hear a sonic boom and all game audio drops out.

Extreme-G is set in the distant future where Earth is reduced into a wasteland. From their new-found planet the human colonists watch their remote controlled bikes wreak havoc through their ancient cities and fight their way to determine which racer manages to qualify.
