Guitar Hero Smash Hits is a spin-off Guitar Hero game featuring a compilation of songs from earlier releases in the franchise. The game's setlist now supports four players in a full band set-up (introduced to the Guitar Hero series in World Tour), an 8-player battle of the bands setup, and all songs are now original recordings from the genuine artists and are all playable in the Quick Play mode without the need to complete the career first.
