Helluva Game

Helluva Game is an unofficial visual novel that transplants you into the demon-filled world of Helluva Boss, waking with amnesia and no memory of your death. Developer amadeen has crafted a premise that leans into the show's dark comedy while building its own narrative around uncovering what happened to you. The setup positions you as a new recruit in an assassin outfit, giving the story framework for meeting the cast of demon characters and pursuing romantic storylines.

The game operates as a choice-driven VN where your decisions shape relationships—most notably with Millie, whose loyalty to her husband Moxxie becomes a player-determined variable rather than a fixed story beat. This player agency extends to how you navigate the mystery of your own resurrection, though as of version 0.1.4a, the game remains in active development with core content still being added. amadeen has confirmed plans to include Loona, Moxxie, Blitzo, Verosika, and possibly characters from the sister series Hazbin Hotel down the line.

The adult content here centers on erotic scenes with the monster girls you encounter; the developer has deliberately left the scope of specific fetishes undefined, preferring to reveal content as development continues. All artwork is hand-drawn rather than AI-generated, which gives the visuals a consistent artistic voice across the game's 12 available screenshots. Helluva Game is free-to-play upon full release, though early access builds are currently Patreon-exclusive. The game supports Windows, macOS, Linux, and Android, making it accessible across multiple platforms.
