How to:
Only load one save at a time!

1. For the solo achievements, play and beat one song on each difficulty
- Go into the store and achievements should unlock
- Use the standard controller and go into hard mode and it should unlock... If not try beating a song w/ it
2. For CO-OP Play a song and just fail to unlock the CO-OP
3. Online achievements play a ranked game and pick Raining Blood and Win the game.

That way is confirmed working...
