AI Transparency Index: Every AI Disclosure on Steam, Tracked and Searchable

Some of the images used in the game were created with generative AI tools. However, all questions, answer choices, facts, and other written content were created and edited by humans.

Generative AI was used during development to create and refine some 2D visual assets, Steam store artwork, trailer imagery, and localization drafts. All output was reviewed and edited by the developer before inclusion. The game does not generate AI content during play and does not connect to external AI services.

The game and assets were created with the assistance of generative AI tools

Generative AI was used to assist in the creation of some visual assets used in the game. AI-assisted assets were reviewed and prepared by the development team for use in the game.

We use it to enhance our code base, design philosophy, and improve our store listing descriptions.

We are actively working to replace all placeholder AI art before launch. While we aim for a fully human-crafted experience, a few minor assets may still remain at release. AI tools were also used to assist with localizing the game and store page. All 3D in-game art was created by human artists or derived from real-world museum photoscans. (See the credits menu for full attributions.)

All images on the store page and game library are derived from AI-generated source images. The game contains images that were generated by the AI during the development process. The developer designed a specific prompt for each image that was requested from the AI and the generated images were stored in the game. No AI is used during the game and no internet connection is used.

Pixel Metropolis is a human-designed, AI-implemented game. As its sole human creator, I am responsible for the game’s design, systems, architecture, quality assurance, extensive testing, art direction, and sound direction. Codex, primarily using OpenAI’s GPT-5.6 Sol model, has generated all of the game’s code and has been used to direct the creation and implementation of its visual and sound assets. The only non-generated assets are a small selection of CC0 sounds.

This game uses generative AI tools in the creation of artwork. This includes store page capsule images and logos, some in-game image assets, and marketing and Steam Community materials. All AI-generated output is reviewed internally before use. No content is generated by AI during gameplay.

Generative AI was used during development to create some character, environment, and prop models, as well as music, sound effects, character voiceovers, and UI assets. These AI-generated assets were subsequently edited and refined by the development team before being integrated into the game.

Generative AI tools were used during development to enhance and refine certain images which included improving resolution, clarity, colour. No AI-generated content is created during gameplay.

Some of this game’s art assets and code are generated by AI.

AI tools were used during development to create pre-generated content. The game's text was translated from English into 16 additional languages using AI translation with automated consistency review. Game artwork and the soundtrack were created by the developer using generative AI tools; every asset was individually reviewed and curated before inclusion. Store page assets (screenshots, trailer, capsule art) depict or derive from this same game content. The game contains no live/runtime AI generation — all content is fixed at build time, and the game runs fully offline.

Generative AI-assisted tools were used during production to create and refine pre-generated visual artwork, synthesized voice-over, and elements of the narrative and English localization. All materials were reviewed and edited by the development team before inclusion. The game does not generate content during gameplay and does not connect to third-party AI services.

Some of the content was co-created with the help of AI.

AI assistance was used in the development of this game. Players are strongly advised to play using mainstream free "flash" AI APIs such as Agnes API or Qwen API — simply fill in your API information in the game settings. For the sake of speed, enabling thinking mode is not recommended. This game contains optional generative AI features. In “AI-Enhanced Narrative Mode”, the game calls the third-party LLM API you provide yourself, generating more immersive event text in real time as you play. This mode is entirely optional: even without connecting any API, you can still fully experience all of the built-in, human-written historical content and the core gameplay. The game will not use your gameplay data to train any models. All AI-generated content is controlled by your own API key and quota, and you are responsible for your own usage.

Some of the artwork in this game — including character portraits, user interface elements, map and battle backgrounds, unit sprites, and visual effects — was created with the help of generative AI image tools, then reviewed, corrected, and assembled by hand before being included in the game. Some sound effects were produced with AI audio tools in the same way. All of this content is generated ahead of time and is fixed in the shipped build. The game does not generate any content while you play, and it does not connect to any external AI service during gameplay.

To improve the game's visual quality and overall player experience, generative AI was used in the creation of some art assets.

Some of the game's art assets were generated with the assistance of AI. All such assets have been carefully reviewed to ensure they do not infringe on third-party rights or violate Steam's policies.

Generative AI was used as a starting point for the game's graphical assets. The majority of these were then manually modified for use in the game.

Our App employs AI-powered image generation tools to aid in the production of visual assets and background artwork for marketing materials, including store page screenshots and preview assets, as well as for full-screen in-game interfaces such as the home screen and event pages.

Generative AI is used for translation in this game.

Some of the artwork, audio, text, and program code in this game were created with the assistance of generative AI tools and were reviewed, edited, and integrated by the developer. The game does not use generative AI to create content in real time during gameplay.

As an individual developer, during development of this game, AI tools were heavily used. I disclose this honestly and transparently. 1. In-Game Assets Illustrations & Art: Unit portraits and the opening cinematic illustrations were generated using AI image models, then manually curated, retouched, and unified in style. All assets were human-reviewed under strict art direction to ensure historical tone and consistency. Opening Cinematic: Subtle motion effects on the illustrations were produced with an AI image-to-video model and assembled by using the Remotion pipeline. Background Music: The soundtrack was generated by an AI music model in multiple takes, then human-selected, mixed, and mastered. Telegram Voice-overs: The historical telegram voice-overs in-game were synthesized by an AI TTS system. Each character's reference voice was human-approved through listening tests before use. 2. Development Assistance Code: Game code was written and debugged with the aid of AI coding assistants. All code was human-reviewed and validated through automated testing. Localization: The game supports Simplified Chinese, Traditional Chinese, and English. The English text was AI-drafted and human-proofread. 3. What Is NOT AI-Generated Historical Text: The telegrams in-game are taken from historical archives, 34 are verbatim transcriptions of the original documents, and 12 were written based on the sources. They were not AI-generated. Terrain & Map: The battlefield map was procedurally rendered from real elevation data (SRTM), not generated by AI. Game Balance & Statistics: Troop strength, Unit Introduction, and values were researched and set manually from historical sources, cross-checked for accuracy and play balance.

Generative AI used for Audio narration

Game code and ui was assisted with Claude

The text used in the game and on the Steam store page has currently been translated primarily with the assistance of AI tools. Most of the graphical assets used in the game are based on real photographs or renders of 3D objects. However, AI-generated imagery was used in cases where no suitable real-world source material was available, or where the available material was insufficient to complete or supplement the required assets.

Some artwork in this game, including background images, was made with the help of generative AI tools.

Assistance with the development of: - Custom procedural 2D animation rig. - Reinforcement learning (RL) layer for player and NPC animations in hand-authored 2D environments. - Base designs for sprites and backgrounds (further iterated by hand using digital editing software like photoshop) No ai tools were used in any capacity for writing or story elements, voice acting, music, or anywhere else.

Store assets, quiz content, and general layout of application generated with AI to help with design and formatting. Human review and edit before any code implemented. This game does not have any AI models running in the background or in-game. All scriptures are public domain.

As part of our early access work, we have used AI-generated images as placeholders for the illustrations on our cards and leader icons. This allows us to iterate quickly and see which game mechanics players like or dislike. We will replace these with human art once we've received enough feedback to finalize what we keep or discard.

Some in-game images, depicting traditional dress, festivals, food, and cultural artifacts, were created using an AI image generation pipeline (Google Gemini through an automated workflow). Every generated image was reviewed, curated, and approved by the developer before it was added to the game. No AI content is generated live during gameplay.

In ALASH, we utilized generative AI as a supplementary tool to assist in creating 2D art assets. Specifically, AI networks were used to help develop certain environment elements, textures, and background images to enhance the unique visual style of our alternate history setting. Please note that all game design, core mechanics, storyline, tower defense logic, and programming code were created entirely by hand by our development team. AI was used solely to support our artistic vision, ensuring that the integrity and soul of the gameplay remain entirely human-made.

As a solo dev, I created or commissioned/licensed the game assets. No 3D assets were AI-generated. AI was used only for some 2D artwork and audio.
