Ultra Kill is a long-running multi-kill announcer line from the Dota series, heard when a player eliminates four opponents within the game’s kill streak window. The phrase became especially familiar through Dota 2 match highlights, streamer clips and esports compilations, where announcer calls help sell the scale of a play. It is still widely used because the wording is simple, the delivery is intense, and even non-players understand that it marks a near-teamwipe level moment.
