Red Alert 2 is a real-time strategy game released in 2000, known for its tense wartime atmosphere and instantly recognisable base alerts that warn players when they are under attack. Short clips from its alert sounds have circulated for years on soundboards and in fan edits, where the familiar warning tone is reused outside the game to signal trouble or a sudden change of plan. Because the sound is short, urgent and easy to recognise, it still works in memes, streams and reaction videos long after the original game.
