Metroid Dread, released by Nintendo in 2021, introduced the EMMI as autonomous robots sent to explore planet ZDR and later turned against Samus Aran. Their patrol areas, known as EMMI zones, became some of the game's most talked-about sections because the robots cannot be defeated normally and catching Samus usually means instant death. Clips of their mechanical audio spread among players sharing tense gameplay moments, and the sound is now reused in edits whenever a creator wants instant, recognisable gaming dread without showing the game itself.
