The line comes from The Elder Scrolls IV: Oblivion, released in 2006 by Bethesda. Imperial Guards became famous online for their aggressive combat barks and law enforcement lines, which players clipped for forums, videos and soundboards. Die, Imperial, Die is one of those short taunts guards shout during fights, similar in spirit to other game barks like enemy spotted. It stayed popular because Oblivion guards are a lasting meme, and the shout still signals instant trouble in gaming edits today.
About this sound
An Imperial Guard combat shout from The Elder Scrolls IV: Oblivion, used in gaming memes and edits for angry NPC moments, chases and sudden fights.
This short clip is an Imperial Guard from Oblivion shouting Die, Imperial, Die in combat. The delivery is loud, hostile and slightly over the top, with that distinctive mid-2000s RPG voice acting that makes every guard sound furious at the player. It lands instantly as anger and threat, even without context, because the guard yells like you have personally offended the entire Empire. Creators use it for that sudden shift from calm exploration to being chased, caught stealing, or starting a fight you cannot win.
