Cannon Barrage is the ultimate ability of Gangplank, a pirate champion in Riot Games' League of Legends, which launched in 2009. The ability calls down a wide barrage of cannon fire onto an area of the map, accompanied by its distinctive booming audio cue. Clips of the sound spread through gameplay highlights, streamer moments and esports broadcasts, where a well-placed ultimate can decide a team fight. It remains popular because it is instantly recognisable to players and works as shorthand for sudden, overwhelming firepower in edits.
