GOG, the DRM-free PC games platform, has publicly apologized after its newsletter for the game The End of the Sun included the Nazi SS symbol, known as the Siegrune. The error was attributed to an 'unfortunate visual association' with the Proto-Germanic Sowilō rune, which means 'sun.' This incident occurred on June 5, 2026, and both GOG and the game's developers were surprised by the oversight. The developers, a Polish couple, stated they were also taken aback and suggested that the inclusion of the Nazi symbol might have been due to an AI recommendation. GOG admitted to several mistakes, including using the wrong logo and failing to check how the newsletter displayed on mobile devices. They clarified that the symbol displayed differently across devices, which contributed to the confusion. Interestingly, the developers pointed out that their game addresses the historical context of ancient symbols adapted by the Nazis, making the incident even more unfortunate.
