Gene Simmons and Metallica's Lars Ulrich are the first pair of rockers confirmed to make motion-capture enabled cameos in Guitar Hero 6. Simmons will act as narrator for a new Quest Mode in which you’ll recruit rock stars for your band and unlock sets of their songs.
The reference to song sets suggests that Guitar Hero 6 will feature batches of tracks from bands rather than just one of two songs. The artists confirmed so far are Queen, Black Sabbath and KISS.
Guitar Hero 6 is due in June with very little details of which Kiss songs will be featured.
