The big innovation in this fall's Guitar Hero entry, subtitled Warriors of Rock, might just be Quest Mode. This story-based progression through the catalog of tunes looks to spice up the experience a bit by incorporating more video game standards like character abilities and boss fights. (Let's hope they are better done than the terrible boss battles of Guitar Hero III.) We've got a video explaining what makes Quest Mode unique, as well as a fresh gallery full of screenshots. There's no keytar to be found anywhere, but it does look like it could be a whole lotta fun.
