The Track Pack disc also lacks a character creator and has no online play, although you can use the AC/DC tracks online with RB1 and RB2. Unlike Guitar Hero Aerosmith, you will not be playing as the band. The good news is that all songs will be available immediately -- no need to wade through "Whole Lotta Rosie" to play "Heatseeker."
And if you're wondering whether or not "Thunderstruck" will be making a cameo on Guitar Hero: World Tour, DeGooyer said that AC/DC are exclusive to Rock Band "for a term" but provided no information on whether or not there will be future DLC from the band. The AC/DC Track Pack will be rocking and saluting in early November.
