Gravity Defied Classic (iOS 版)

Gravity Defied is an iconic motorcycle trial racing game bringing realistic physics to the mobile platform. It was originally developed by Codebrew Software. The objective of the game is to race as quickly as possibly through the obstacle-ridden courses. The robust physics engine allows for both racing and trial style challenges. Whether you are trying to maintain good traction along the racing course or gain maximum altitude to overcome an obstacle, reality is realisticly mirrored. No two challenges are the same and almost any challenge can be solved using different approaches.
