"Monster" is a song recorded by American indie rock band Imagine Dragons for the soundtrack to the 2013 Chair Entertainment and Epic Games Action role-playing game Infinity Blade III.
Speaking of the song, the band have stated:
"Chair has always been on the cutting edge of mobile gaming. Infinity Blade has been massive and we felt the song fit perfectly with the tone and visuals. We're pretty big gamers ourselves, so we couldn't be more excited"
Awesome song!
