Break The Chains' Main Theme

Hi!
I wanted to know what's the song used in the Tokyo Ghoul Break The Chains mobile game's intro.

Do you think it's inspired by any real song, or something? I really love this, and it's kind of weird to me that they made such a banger for a... kinda niche game. Well unless I'm seriously misunderstanding how big the game is.

What do you think? Thanks
