Garry's Mod is a physics sandbox game built on Valve's Source engine, where players build scenes, stage machinima and experiment with weapons and props. Short weapon sounds from the game have circulated for years on soundboards and in fan videos because they are instantly recognisable to players and easy to drop into edits. This loopable version is popular for the same reason: it can be repeated for sustained fire without an editor having to search for a longer recording, keeping gameplay montages and comedy sketches fast and punchy.
