Jay-Z and Eminem are to release previously unheard material as part of a special edition of the forthcoming video game DJ Hero.
The package, entitled DJ Hero: Renegade, which is named after their 2001 collaborative single, will also include a copy of the game and a special Renegade turntable controller.
Fans will also receive a double-CD containing unreleased songs by both artists.
The special edition will be released at the same time as the standard instalment of DJ Hero in October.
The game, which has been created by the makers of Guitar Hero, allow users to interact with an electronic turntable.
Bobby Kotick, CEO of developers Activision Blizzard, told said recently that people would be able to “play competitively and spin discs and mix songs”.
