You can download the piano sheets of the soundtrack Battle Theme for free. Let me know if you were able to follow the sheet by writing me on my YouTube Channel: PianoCat. Also don’t forget to check out the next Soundtrack “City of Ruin”.
Nier: Automata was released on February 2017 by Square Enix and I really fell in love with the Soundtrack. This sheet music is for slightly advanced players. If you don’t have the game yet, definitely go and get it!
