DJ Hero 2 boasts "full microphone support" with "integrated on-screen singing and rapping" and "freestyle gameplay giving virtual DJ's the ability to crossfade, scratch and sample in over 70 speaker-blowing mashups" plus mix battles, according to Activision.

Tracks from arists including "Dr. Dre, The Chemical Brothers, Kanye West, Metallica, Lady Gaga, Rihanna and over 85 others" will be featured in DJ Hero's mixes created by producers including Deadmau5, who will also be a playable character.

Talking about DJ Hero in January, Activision CEO Bobby Kotick admitted that "if you're going to make a commitment to doing something original, the odds are that you're not going to get it right on the first chance," and vowed "We'll stick with it and get it right."

DJ Hero 2 slams onto Xbox 360, PlayStation 3 and Wii this fall and will be available on its lonesome, with one turntable in the 'Turntable Bundle,' or with two turntables and a microphone in the 'Party Bundle.' Pricing has yet to be revealed.

To celebrate the news, Activision is releasing a mix of Lady Gaga's "Just Dance" and Deadmau5's "Ghosts 'n' Stuff" for free on Xbox 360 and PS3 "from June 8-14."
