Made by , Guitar Rock Tour follows the rhythm music game play method made familiar by Guitar Hero and Rock Band. Music plays, notes appear on the screen, and you have to hit them in time. The songs included with Guitar Rock Tour are covers of popular rock-and-roll tunes spanning the last few decades--everything from The Killers' "Walk Idiot Walk" to "Smoke on the Water," as made famous by Deep Purple.
Just like in Guitar Hero, there's a career-style "tour" mode that puts you in an up-and-coming band, making its way through various venues spanning the world. As you play each gig successfully, you'll unlock new songs which you can also play individually in a quick mode.
There are three difficulty levels--easy has you picking out individual notes, while medium and hard introduce more notes, chords and faster speed. Each requires you to hold the iPhone or iPod touch a different way to get the right grip; all three will tire your fingers and hands out pretty quickly. It takes a lot of dexterity to get the balance right.
The actual mechanics of the game are startlingly similar to Rock Band and Guitar Hero--if you miss a note, your guitar will make a sour note, the playing of the song will be disrupted, and the crowd will turn against you. Drop enough notes and your gig will be cancelled all together. These game play elements mercilessly imitate Rock Band and Guitar Hero, but they also make Guitar Rock Tour distinctly different from Tap Tap Revenge, which doesn't disrupt music playback at all if you miss a note. Personally, I find this style of play more compelling and more challenging, because the audio feedback of hitting the note right--including sustained notes--adds to the challenge, and makes you feel more in control of what's happening on the screen.
Do well and you'll be awarded with point multiplier bonuses. You can also build "pyro power" by hitting series of notes that look like they're on fire: When your pyro power meter is full, you flip the switch and the crowd goes wild and your points double for the duration.
