Guitar Hero: Warriors of Rock features the heaviest narrative focus of any Guitar Hero yet. An epic hero battles an ancient evil with mighty axe, (get it?), but the hero is defeated. Entombed in stone, the hero's axe is lost, and the evil slumbers. But the evil awakens again and and it's up to the characters of Guitar Hero tiltles past to discover their rock-powered true selves in order to take the fight to the Beast. In practical terms, this boils down to unique abilities reminiscent of call of duty's perk system. Each character has a particular talent- Casey Lynch has a streak guardian, w/c protects a multiplier from a missed note, while Lars Umlaut can build a 5X multiplier rather than the usual 4X.
