The shorthand MW2 points to Call of Duty: Modern Warfare 2, the 2009 first-person shooter whose weapon sounds became a staple of gaming soundboards. Shotgun blasts from the game were ripped, trimmed and shared as short clips for edits, streams and memes, where a single loud shot could signal a kill or a dramatic turn. Because the sound is instantly recognisable to FPS players and needs no context, it remains a useful punch effect for creators long after the game's release.
