Killtacular comes from Halo Reach, released in 2010 as Bungie's final Halo game, where announcer Jeff Steitzer called out multi kill medals inherited from earlier entries in the series. Earning it required five kills with only a few seconds between each one. Clips of the call spread through YouTube montages and forums long before modern soundboards, and it sits alongside other shooter callouts like enemy spotted and bomb has been planted that editors reuse outside their original games. Its exaggerated delivery keeps it popular as instant shorthand for dominance.
