KOG Studios is a South Korean game developer founded in 2000, best known for Grand Chase and Elsword. Its logo sting has accompanied game launches and trailers for those titles, so players hear it before character selection and opening cinematics. As clips of intros were shared online, the sound was separated from the video and reused on its own as a recognisable gaming startup cue. It remains popular because it is short, clean, and instantly signals a Korean online game aesthetic without needing any dialogue or music.
