Metal: Hellsinger

The game mixes elements from both first person shooters and rhythm games, drawing particular reference from the rebooted Doom franchise. While navigating the demonic game world, players are faced by an array of demons and accompanied by a heavy metal score. Players deal extra damage if their attacks are synchronised to the beat of the music, with additional instruments joining the song as the fury meter increases. This meter can also be maintained by performing other actions, such as dashing and reloading, to the beat.

This beat is also represented in environmental elements, such as fire animations, in what the game calls the "natural rhythm of the universe". Additional challenge levels named Torments can be beaten to unlock power-ups.

A lost soul named simply "The Unknown" arrives in Hell, whereupon her memories, her voice, and her "song" are stolen, as Hell steals the memories of all who reside there, sometimes leaving just enough to make inhabitants suffer. Seeking to reclaim it, she goes to face the ruler of hell, The Red Judge, but was locked away behind an unbreakable Anguish Gate below the Hells. However, she is called upon and finds Paz, a talking skull who acts as the game's narrator, and whose power, his "pulse" that is the "rhythm of the universe", is something Unknown can harness as her own "song" to break through Anguish Gates and ascend through the Hells back to the Red Judge to reclaim her voice.

Heading to the first Hell, Voke, Unknown and Paz fight their way through the demons and kill an Aspect of the Judge, weakening the Red Judge's power while restoring a portion of Unknown's voice and Paz' memories. Discovering Paz's survival after believing him destroyed, the Red Judge sends the armies of hell to stop The Unknown and her other Aspects to guard the other Hells. As Unknown heads to the second Hell, Stygia, and kills another Aspect, the Red Judge, after researching the Unknown, finds a prophecy that states that the Hells will fall when an Archangel is slain at the Infernal Throne by a Hellsinger. Determined to prevent Hell's prophesied doom, the Red Judge attempts the "Ritual of Spears" to bind Unknown to her will after she battles through the third hell, Yhelm, but Unknown resists it, causing the Red Judge to slowly become panicked as Unknown reaches the fourth Hell, Incaustis, and defeats another Aspect, convincing the demons that Unknown is the Hellsinger.

Development began in the wake of the cancellation of The Outsiders' previous game, Darkborn. The team decided to use their own music, rather than existing metal, out of both budgetary restraints and the technical need to split the music into layers for the fury meter system. The game was announced in June 2020, initially billed for a 2021 launch, but was delayed to 2022 "in order to meet the high expectations for the game".

In October 2025, it was announced that The Outsiders was being shut down by its parent company Funcom. David Goldfarb, the studio's founder and creative director announced the closure.

Eurogamer was positive about the game, noting that it "feels like an outpouring of emotion, as though the game itself is also a different, more personal kind of gestalt," beyond its references to the genre. IGN's review was more mixed, stating that while the game was good it was very short and the bosses were repetitive, adding "Metal: Hellsinger might not be the greatest demon-slaying shoot 'em up in the world, but it's certainly a stirring tribute". PC Gamer had a similar assessment, adding that it while it was unlikely to impact the genre, it was "a perfectly fine game with lots of replay value, some neat ideas, a good soundtrack and a goofy story."

More than 1 million copies of the game had been sold by December 2022.
