In Warframe, Necramechs are large, pilotable war machines that players can build and control, first introduced in the Heart of Deimos update. Their heavy, industrial audio design sets them apart from the sleeker Warframes, which is why short clips of their movement and activation sounds circulate among players. Fans reuse the sound in gameplay videos, edits and memes to signal something huge and mechanical arriving, keeping it popular as Warframe's mech content continues to feature in community videos.
