Stunt Playground for Mac
A software developer has successfully ported Stunt Playground to Mac. The fully 3D stunt driving game features realistic physics that are fully integrated into both the driving and the editor. Users can arrange various props and jumps as desired, and can save as well as load creations for later. Players can record instant replays of up to 15 seconds in length while driving and play the clips later from any angle. Stunt Playground is available for free, as is the game's source code.
Stunt Playground boasts an open-ended sandbox style of gameplay, allowing users to save as well as load custom arenas and instant replays. Real-time shadows and reflections accompany a total of eight vehicles to choose from with different physical properties.
