"Master of Puppets" is an tier 6 song featured in Guitar Hero: Metallica. It is a long song that includes strange time signatures interspersed within the song, as well as a oddly charted main riff.
The ending note on Expert Guitar is a G-R-Y-B chord, one of the few songs in the franchise to utilize a four note chord. Due to the much needed strumming, very fast speed, very long time period and very hard solo, "Master of Puppets" might be considered very hard indeed, but still lacks that craziness that makes it as hard as "Dyers Eve" and "War Ensemble", arguably the two hardest songs in the game.
