What is "gripshift"

GripShift is a hybrid title video game that was developed by Sidhe Interactive and co-published by Red Mile Entertainment, Sony Online Entertainment and Ubisoft Entertainment for the PlayStation Portable handheld in 2005. The game was later released for download on PlayStation 3 via the PlayStation Store (it is no longer available for purchase since 2014), and for the Xbox 360 via Xbox Live Arcade. GripShift is a cross between a platform/puzzle game like Super Monkey Ball and a driving game like Stunt Car Racer.
