Echo Slam comes from Dota 2, Valve's multiplayer online battle arena game released in 2013, where Earthshaker is one of the original strength heroes. His ultimate sends damaging shockwaves through nearby enemies, making it a favourite for turning team fights around. The sound has spread beyond matches through highlight reels, streamer clips and edited gameplay videos, where its heavy impact signals a decisive moment even to viewers who do not play the game. That instant recognition keeps it popular in gaming edits years after release.
