Half-Life 2, released in 2004, is a science-fiction shooter set in City 17, a city controlled by the alien Combine, and its alarms are part of the game's oppressive atmosphere. This version carries the warning in Russian, reflecting the game's localised audio and the Eastern European feel of its setting. Clips from the game have circulated for years on soundboards and in edits, where the danger alarm sound effect is reused to signal trouble instantly. It remains popular because players recognise the Combine world at once, and the stern announcement still sounds urgent outside the game.
