Let it Die: Inferno Quietly Built With Broad Generative AI, And Most Players Wouldn’t Know

Let it Die: Inferno, the sequel to Grasshopper Manufacture’s cult 2016 action game, is set for release next week—and it’s already sparked debate by disclosing a heavy reliance on generative AI for its voices, music, and visuals. If Steam didn’t mandate these disclosures, most players might have never noticed.

The Steam store page for Let it Die: Inferno now spells it out: “AI-generated content has been used and then edited by our team for certain parts of the in-game voices, music, and graphics.” That’s not just a little bit of background wallpaper, either. The developer lists background signboard textures, records illustrations, infocast videos, plus both voices and music. The exact breakdown isn’t detailed, but the footprint of AI-generated content here is substantial.

This sequel arrives from Supertrick Games, not original studio Grasshopper Manufacture, a key distinction, since Supertrick was only the co-developer on the first game. There’s a major gameplay update too: instead of the original’s asymmetric multiplayer and base infiltration, Let it Die: Inferno pivots to a PvEvP structure, promising “real-time multiplayer.” That’s sure to shift the competitive dynamics for returning fans.

The new game was a surprise when it dropped into the world in September during a PlayStation State of Play. Before that, no leaks, little hype. And now it’s out just a few months later. The rushed marketing cycle, paired with deep generative AI usage, suggests the project’s timeline may have been accelerated by automation. AI tools can churn out assets, voice lines, and even music at dizzying speed; when deadlines are tight, corners can get cut.

But if it weren’t for Steam’s specific rules on AI content, none of this would be public. Most players would never know whether that voice or background art was human-made or spun up by a machine. That’s significant transparency, and it gives observant shoppers the info they need, if they care about such things.

This isn’t the only game sneaking AI into the mix, but explicit disclosure remains rare. Industry leaders like Epic Games CEO Tim Sweeney see transparency rules as pointless. In his words, AI usage will soon be so universal that there’s “no sense” in forcing each title to spell out exactly where the tech was used. Others are glad for the warning, especially as the line between handcrafted and algorithm-made art gets increasingly blurry.

The scale of AI in Let it Die: Inferno matters. Music and voice touch the heart of game immersion. Art and video shape every moment you’re behind the controller. With so many core elements getting the AI treatment, fans have to decide for themselves: are they open to algorithmic creativity in their games, or does it make the experience less authentic?

One thing’s certain: this disclosure will influence conversations; not just about this game, but about the future of development tools, creator credit, and maybe even how games get made on a deadline. When Let it Die: Inferno launches on December 4, it’s not just a new chapter for the series. It might be a preview of how the industry handles AI in everything from indie passion projects to big-budget sequels.
