DJ Hero 2 and Guitar Hero 6 demos available on Xbox Live

The Hero games are invading Xbox Live Marketplace, with demos available now for both the upcoming DJ Hero 2 and Guitar Hero: Warriors of Rock.

The DJ Hero 2 demo will feature four mixes: Pussycat Dolls Featuring Busta Rhymes “Don’t Cha” Mixed With Pitbull “I Know You Want Me (Calle Ocho)”; Lady Gaga Featuring Colby O’Donis “Just Dance” Mixed With Deadmau5 “Ghosts N Stuff”; MSTRKRFT Featuring N.O.R.E. “Bounce” (Battle Mix); and Estelle Featuring Kanye West “American Boy” Mixed With Chic “Good Times”.

The Warriors of Rock demo will give players the first look at the game’s “Quest Mode,” a story mode narrated by KISS rocker Gene Simmons where you’ll transform the game’s characters into rock warriors to… kill a rock demon or something. I don’t know. The demo will feature four tracks: Black Sabbath’s “Children of the Grave,” Foo Fighters’ “No Way Back,” Slash’s “Ghosts” (featuring Ian Astbury), and Dethklok’s “Bloodlines.”

They’re both available now for Xbox Live Gold members. Go get ’em.
