The "In the Moment
," "Star Powered
," "A Cool Mill
," "There's no I in Band Hero
," and "Four of a Kind
" achievements can all be unlocked in one song playthrough by yourself using this method.
1. Play the song "Grave of Opportunity
" by Unearth with four Expert vocalists. The song contains only talking, and is a free download
: All Guitar Hero DLC has been removed from Xbox Marketplace
, but if you previously downloaded the "Ferret/Metal Blade Track Pack," you can, of course, still use this song to unlock these achievements.
2. Place your combination of USB microphones and Xbox 360 headsets, while connected to each of the four controllers, in front of a running fan. This will provide a constant source of sound for the microphones and headsets, and play all of the notes perfectly, even on Expert difficulty (because the song only has talking).
3. Save up all of your star power until after you have successfully passed the first "Band Moment," when you should press the A button on all four controllers at the same time. You will be able to tell whether the "Band Moment" has been successfully passed by whether the borders of each note highway are a fiery orange color. This will give you an 11x multiplier for the entire band.
At the end of the song, I had 1.9 million points, and unlocked 5 different achievements in about 4 minutes of gameplay! If you don't personally own four controllers and a total of four headsets or microphones, you can follow this same method online with your friends.
