 Guitar Hero : Warriors of Rock is the sixth installment in the franchise and introduced a new take on the Career mode of previous games . Rather than being a quest for fame and glory with the band travelling through different venues , Warriors of Rock features the " Quest Mode " as the primary campaign mode . Quest Mode tells the story of an ancient warrior who was defeated by a powerful monster and his mystical guitar was lost . The player must <unk> a team of rockers to help recover this guitar and defeat the monster ( called " The Beast " ) . As the player progresses through the mode , the rockers joining them will transform based on the number of stars earned from songs played . These <unk> will <unk> the player with extra abilities in a song such as constant score <unk> or Star Power bonuses . These abilities are each unique to the individual rockers and by using them effectively , it is possible now to earn up to forty stars for a single song .
