Activision have announced a special edition of DJ Hero which will spawn from the loins of a collaboration between Jay-Z and Eminem:

Jay-Z and Eminem will contribute some of their popular songs to DJ Hero and will collaborate on a special branded edition of the game that will include an advanced version of the game’s turntable controller, a metal traveling case that transforms into a performance-ready DJ stand and two exclusive music CD compilations featuring greatest hits and new mixes from each artist. Jay-Z and Eminem will both provide downloadable content later this year that will give DJ Hero fans fresh mixes of their material.

The artists also have a few things to say about it:

“A DJ has the ability to use music to control people's emotions and is responsible for the entire vibe of a room, a club or a party,” said Jay-Z. “DJ Hero is the first video game that allows everyone to enjoy the unique experience of creating that environment.”

“I came up doing freestyle battles on local stages with other MCs and DJs,” said Eminem. “DJ’ing is an essential part of hip-hop and DJ Hero will give people all over the chance to experience the music from the other side of the turntables.”

We've also got two short videos showing off the gameplay at different difficulty levels - Easy and Medium, so check them out for a look at the action.
