A London Underground advertisement for Nintendo's upcoming game Metroid Prime 4: Beyond mistakenly claimed the game was "out now," causing confusion among fans. The poster, spotted in London, displayed an "out now" banner that was not accurate. Nintendo confirmed that the messaging on the advert was incorrect and that the game had not yet been released. The error was attributed to Nintendo sending out both "out now" and "coming soon" versions of the advertisement, with the wrong one being displayed publicly. Speculation based on the advertisement suggests a possible release around August 2025, following Nintendo's July release of Donkey Kong. After three days, Nintendo corrected the London Underground advertisement to remove the inaccurate "out now" claim.
