Killer Instinct began as a 1994 arcade fighting game from Rare, and the Ultra Combo became one of its signature finishes, a long string of hits capped by a dramatic final blow. The announcer call and escalating combo sound became instantly recognisable to fighting game fans, and the series revival in 2013 brought the phrase back to a new generation of players. Since then, clips of the call have circulated widely in gameplay montages, streams and meme edits, where it works as shorthand for an unstoppable run of success.
