Harmonix has announced that a new difficulty for Rock Band 4 is coming in the December update.
It is called Brutal Mode, and it is a step above Expert. The note patterns will change based on how well you’re playing a song. If you’re doing well, the note patterns get harder.
You’ll also be able to win Crimson Stars in Brutal Mode, the next level after Gold Stars. Check out the video below to see Brutal mode in action.
