DJ Hero 2 is a rhythm video game and a sequel to DJ Hero, a spinoff of the Guitar Hero series. DJ Hero 2 uses a special turntable-controller, the same as introduced in DJ Hero, 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 is developed by FreeStyleGames and is published by Activision, and was released worldwide in October 2010.
