"DJ Hero 2 is a rhythm video game and a sequel to DJ Hero. DJ Hero 2 uses a special turnable-controller to simulate turntablism, the act of creating a new musical work from one or more previously-recorded songs using record players and sound effect generators. The game will continue to be developed by FreeStyleGames and published by Activision, and is expected to be released worldwide in October 2010."
