Veteran music videogame developer Harmonix Music Systems has been busy in-studio, enriching this rockstar experience with more features and multiplayer modes. In addition to the traditional head-to-head competition, Multiplayer Co-op Mode allows players to collaborate in order to beat songs, with each guitarist playing a separate guitar track. Available guitar tracks include lead, rhythm or bass tracks, depending upon the song. The Guitar Hero SG Controller used in the first installment will also be compatible with the new game.
- The top-secret sequel song list remains firmly in the rock domain, pulling from a mix of classic rock, 'hair' metal, heavy metal, modern rock, and alternative titles. More than 55 songs will be featured in the next installment.
- Guitar Hero II arrives with a new track list, new venues and additional play modes – including the ability to transform the original Guitar Hero SG Controller into a rhythm, lead or bass guitar.
