Australian developer House House said it used generative AI sparingly, mainly to debug Big Walk's code, and estimated well under 0.1 percent of the code related to that use. The disclosure, made in a statement to Aftermath, followed the Independent Games Festival judging fallout, in which 19 IGF jurors said they would not vote for any game that used generative AI during development. House House said it had not disclosed the use on Steam because the platform does not request code or chatbot disclosure, and it posted the statement because the matter had become one of public interest. The studio said it was not endorsing AI use, apologised that the usage may not meet critics' standards, and called the lack of an internal AI usage policy a failure it would address. Eurogamer, which gave Big Walk five stars in its review, said the revelation is likely to leave a taint on one of the year's brightest games. House House said LLMs were used to research issues with third-party code through chatbots, and that some response snippets were copied as starting points for game code. Eurogamer reported that the revelation is likely to taint the game's reputation to some degree.
