Killtacular is part of Halo's long-running multi-kill medal system, voiced by announcer Jeff Steitzer, whose calls have defined the series since Halo: Combat Evolved in 2001. In Halo: Reach, released in 2010 by Bungie, the medal requires four kills each within four seconds of the last. Steitzer's escalating series from Double Kill to Killtacular became cultural shorthand for dominance in shooters, alongside other iconic FPS calls like the bomb has been planted announcement. Clips of the voice line still circulate in montages, memes and soundboards long after Reach's servers peaked.
