Infinite Guitars

Just for clarification: this appears to relate to songs used in battle only. So for this achievement all you have to do is get 100% sync rate for any song during battle. This will be simple if you chose easy mode when beginning the game (basically say you are not a fan of rhythm games when prompted and you can choose between easy or normal - if you say you like them you only get options of normal and hard).

I believe the other guide on here is now outdated, as this achievement (and the ones for five and ten 90%+) do NOT have to be obtained during battle. In fact, this was the first achievement I unlocked during the tutorial on opening doors via the red guitar sword switches.

Couple tips for this:

1. This can be obtained on Easy mode for the Rhythm Game Difficulty setting. This setting is chosen via dialogue option when starting the game, but can always be changed in the menus, under Difficulty. (Easy mode allows for less notes/less complicated button-pressing during songs).

2. Any song will count for this achievement. In other words, it does not need to be in a battle. Any song that requires you to hit , , and in rhythm will count. This includes opening doors or activating the hand blasts via the guitar swords. I believe an old version of the game only counted songs during battle, but I obtained this achievement (and the one for one 90% sync) via red guitar sword door switches.

3. If you're trying to knock this out quickly, make sure you choose attacks other than the first (1/x) attack, Guitar Smash. That attack has you holding and releasing for damage and is used for the Critical Hit achievements. Instead, focus on always using either Ruckus Punch, Burst Cannon, or Fist Impact.

4. The songs the game has you play seems to be random each time you're required to play (battles, opening doors, etc). This should unlock for you somewhere at the start of the first chapter if you're pretty decent in getting the 90% sync.
