Hearts of Iron IV is a grand strategy game by Paradox Interactive, released in 2016, in which players guide a nation through the Second World War era. World news events report major developments around the globe as the campaign unfolds, and their distinctive alert became familiar to players through long playthroughs, streams and gameplay videos. Editors later lifted it for memes and parody news edits, where its official, historical tone makes even a small in-game or real-world update feel like a major global announcement.
