Big Walk developer reveals it used generative AI 'sparingly', estimates 'well under 0.1%' was actually coded using LLMs

House House, the developer behind the popular cooperative puzzler Big Walk, has sparked a new debate over the use of generative AI in game development. In response to comments from jurors at the Independent Games Festival awards, the studio has acknowledged that it employed LLMs sparingly during the final stages of Big Walk's development.

The company estimates that less than 0.1% of the game's code was influenced by AI-generated content, and it was not used for any other purpose. House House clarifies that the platform Steam does not require disclosure of AI usage, but the studio decided to make the revelation as it has become a matter of public interest. The developer emphasizes that this is not an endorsement or argument for the use of AI tools, but rather an admission of a lack of policy in place and an intention to develop a more comprehensive one in the future.

Despite their support for the pro-Palestinian movement, Big Walk's use of generative AI has raised questions about the studio's stance on AI in game creation.
