Half-Life was released by Valve in 1998 and made the crowbar the defining weapon of its silent protagonist, Gordon Freeman. Players spent much of the game swinging it to break crates, open vents and fight headcrabs, so its whoosh became one of the most repeated sounds in PC gaming. As Half-Life grew into a landmark series, the crowbar turned into a wider internet symbol, referenced in mods, Garry's Mod videos and the crowbar meme, keeping the original swing recognisable decades later.
