Early last year, while working on the next entry in the Life Is Strange franchise, a few developers at Deck Nine stumbled upon something that didn’t belong in their game: Nazi symbols.

Initially, developers noticed a reference to the number 88, and flagged the issue to their bosses assuming it was an innocent mistake. But in the ensuing weeks, others found more problematic signs and in-universe labels, such as references to a racist memethe number 18, and the Hagal rune. As the number of possible hate symbols mounted, staff grew increasingly concerned that someone was putting these items in their game deliberately as a dog whistle to white supremacists.
