Unreal Tournament launched in 1999 from Epic Games and became known for its arena matches and escalating kill announcements. Double Kill, Multi Kill, Ultra Kill and Monster Kill rewarded rapid streaks, with the announcer growing louder at each tier. Clips of those calls spread through early gaming forums, frag videos and later meme edits, sitting alongside other shooter callouts like enemy spotted in stream soundboards. The phrase survived because few other games made a four-kill streak sound so dramatic, so it still marks dominance in modern FPS clips.
