Metal: Hellsinger is a first-person shooter with rhythm game elements in which your success depends on your ability to fight in unison with the music. The more accurately you get into the rhythm, the more expressive the music sounds, and the more destructive your attacks become. Players will be asked to take on the role of a certain Nameless One, a half-human, half-demon obsessed with a thirst for revenge. You have to fight in the terrible corners of hell and destroy hordes of demons and their leaders. At the end, players will have a fight with the dangerous Scarlet Judge.
