Was your taste of the new peripherals in Guitar Hero: Warriors of Rock not enough? Well, the attached video should satiate your desires for now, as it actually shows you how the customization works -- sans hands! It's all very Transformers like.
If all of the CGI wizardry in the video, found after the break, isn't your style, feel free to give our high-res images in the gallery below a looksee. Just don't look too closely -- we wouldn't want you transforming into a ManBearPig or something.
