Echo Slam has been Earthshaker's ultimate since his days in the original Defense of the Ancients mod, and it carried over into Dota 2, released by Valve in 2013 for PC. Earthshaker became known for turning crowded team fights with a Blink Dagger initiation followed by this ability. Clips of big multi-hero slams spread through tournament broadcasts, highlight reels and streaming culture, making the sound instantly recognisable to MOBA players. It remains popular in edits as a shorthand for a sudden, fight-winning impact.
