It was only a matter of time before new gaming interfaces emerged in the mobile gaming market. With the introduction of the iPhone and some select Sony handsets accelerometers are now all the rage which means they can be used as input devices for games. Handmark did just that with their latest game, GTS World Racing.

GTS World Racing offers a unique mobile gaming experience utilizing the iPhone built-in accelerometer feature. Players can accelerate, brake and steer the car by moving and turning the device itself. The game includes 64 track layouts and offers a choice of multiple car types and difficulty levels, as well as 4 exciting play modes - Single Race, Challenge Cup, Grand Tour, and Championship.

In addition to the unique interface and use of the accelerometer feature, GTS World Racing offers players a choice of music options. Users can select the exhilarating music soundtrack or use the music from their iPod to create their own customized racing soundtrack.

GTS World Racing was jointly developed by Astraware, the Handmark Game Studio, and Pazzazz Games.
