You can download the piano sheets of the soundtrack Halo wars 2 – Cratered for free. Let me know if you were able to follow the sheet by writing me on my YouTube Channel: PianoCat.
Halo wars 2 was released on February 2017 by Microsoft Studios and this soundtrack was composed by Gordy Haab, Brian Trifon and Brian Lee White. This sheet music is pretty easy to play so give it a try! And if you don’t have the game yet, definitely go and get it!
