Hellternum is developed by a small independent studio. Some visual elements — certain in-game illustrations, textures and marketing images — were produced with the help of generative AI tools, always under direct human art direction and edited by hand to fit the game's visual identity.
Everything else is human-made: design, writing, level design, code and audio.
We think you should know this before you play.
Generative AI was used during development to assist in creating some of the pre-generated visual assets. All such assets were manually selected, modified, and integrated by the developers. The game does not generate content in real-time during gameplay, nor does it connect to external AI services.
PER MY LAST EMAIL contains pre-generated AI content. Its music is created with generative audio tools; its sound effects are CC0 recordings, not generated. Its narrative text is human-AI co-written and human-edited under the author's direction; the game design is the author's. Its store artwork uses AI-generated background plates, composed and finished programmatically; the game's own user-interface elements are drawn in code and contain no AI-generated images. No AI content is generated at runtime, and the game contains no AI-generated depictions of real people.
Portions of this game's artwork were created with generative AI tools under human direction, curation, and editing — including aircraft counter sprites, scene illustrations, character portraits, achievement icons, and some store/marketing images. The store trailer's narration is AI-generated voiceover. Some code was developed with AI assistance and human review. The game does not generate any content with AI while running.
Some Steam store graphical assets for VN Engine 2D, such as capsule and library artwork, may have been created with AI assistance and were manually reviewed before submission.
VN Engine 2D is a desktop editor for creating 2D visual novels and interactive story projects. The Steam build does not include player-facing live AI generation, does not connect to external AI services during use, and does not require users to enter third-party API keys or pay for AI services outside of Steam.
1453 contains pre-generated AI content: in-game illustrations and short ambient video clips created with generative image/video tools, curated and edited under human art direction and reviewed for historical accuracy. The narrative text is human–AI co-written and human-edited under the author's direction; the game design is the author's. No AI content is generated at runtime.
It was found that some character art pieces in the game used AI references after artists received explicit instruction and legal binding not to use AI.
This will be rectified in the future. I am committed to providing a game without AI usage.
Generative AI was used during development to assist in the creation of certain visual assets, including some textures and artwork featured in story sequences. All generated assets were reviewed, modified where necessary, and curated by the development team before inclusion in the game. No AI-generated content is created during gameplay.
This game uses AI-assisted tools to create character voices. All dialogue was written, directed, edited, and implemented by the developer to fit the characters and story.
This game includes pre-generated content made with the assistance of generative AI tools during development. AI tools were used to help create and iterate some static story illustrations, character and store-art references, voice and sound-effect materials, texture details, copy polishing, and localization drafts. All such content is selected, edited, assembled, and manually reviewed by the developer before shipping. The game does not connect to a live generative AI service during play and does not generate new player-facing AI content at runtime.
We used a Gen AI powered tool to localize the following:
- (in some languages) In-game text
- (in some languages) Steam store descriptions
We plan to replace these with human translation and LQA when we can afford it.
Until then, we are using Gen AI temporarily.
Localisation: The game's interface text was localised into 11 languages (French, Spanish (Latin America), Italian, German, Portuguese (Brazil), Russian, Simplified Chinese, Korean, Japanese, Polish, Turkish) with the assistance of AI tools. All original English source text was written by the developer.
Voice-over: Some in-game voice-over was created using AI voice generation, used alongside recordings from real voice artists.
Music: Two background music tracks heard on in-game radios were generated with AI tools, then filtered and edited by the developer in FL Studio.
Store art: The capsule artwork combines a hand-made logo created by a commissioned artist with an AI-generated background.
AI tools were used in a limited capacity during the development of the game, primarily to assist with certain programming tasks and the creation of temporary assets.
No AI-generated content is created in real time while playing the game.
All of the game's text was written by hand by Yohan Dupuy and translated by a qualified professional to achieve high-quality literary English (not AI). AI is only used partially for the visual and audio presentation.
Some sound effects and a small number of textures in this game were created with the assistance of AI tools and refined by hand. Subtitle translations across our nine supported languages were generated using AI from the original English voice acting. Voice acting was performed by real people, with AI tools used only for noise reduction and audio mastering. All AI-generated content was curated and finalized by human creators before being included in the game.
The Event currently includes three AI-generated projector scenes used only as temporary placeholders, pending replacement with human-made artwork in the near future.(feel free to contact me for any possible collaborations)
Aside from these placeholder scenes, the remaining voice work, including the double voice effects, was created directly by the developer.
Generative AI was used to create some in-game radio audio, including text-to-speech announcements and background music tracks generated using AI tools.
Some background music in this game was created with the assistance of generative AI tools. The final selection, editing, and implementation of the music were handled by the developer.
The only use of AI has been to translate the game subtitles and menus.
The translation has then been reviewed in Polish and French by native speakers, but might contain oddities in the other supported languages.
This game uses generative AI tools during development.
All voice-over audio is generated using AI tools.

Some promotional capsule artwork for the Steam store page was created with the assistance of generative AI tools. No AI-generated content is used during gameplay
Heart Duels is a solo-developed game. I use AI-assisted tools for some art and audio. All assets are curated and integrated by me to create a cohesive experience.
Pre-generated AI tools were utilized to create the foundation for the 2D background art, character sprites, and audio. All of these raw assets were then extensively edited, cropped, and manually integrated by hand to ensure they perfectly fit the game's mechanics, atmosphere, and engine requirements.
This game uses a local AI language model to generate the NPC's dialogue in real-time during gameplay. All AI processing runs entirely on your device using bundled software, no internet connection is required and no data is ever sent to external servers or third parties.
Empetiti: Quest for the Pinnacle uses generative AI as part of the production pipeline for selected images and voice-over/audio assets appearing in the game and some promotional materials. These assets are reviewed and refined by the development team before being published. The game does not use live-generated AI during gameplay.
THE GAME IS CONSTANTLY BEING REWORKED TO FURTHER MINIMISE THE USE OF AI-GENERATED IMAGES AND VOICES.

Some of the music/sound effects in this game were arranged or edited with the assistance of generative AI tools. All AI-generated audio was reviewed and curated by the development team.
Generative AI was used during development to draft initial art concepts and assist with the foundation of text localization. All final in-game visual assets were manually refined, edited, and finished in Photoshop to ensure a high-quality, hand-crafted aesthetic. Localization was human-reviewed to ensure accuracy for players.
A few select original assets were refined with AI assistance and finished by hand to match the game's atmosphere. No AI content is generated during gameplay.
