The sound comes from ULTRAKILL, the fast-paced retro first-person shooter developed by Arsi Hakita Patala and published by New Blood Interactive. The Earthmover is one of the game's enormous boss-scale machines, and this hurt noise plays when it receives damage. ULTRAKILL's loud, exaggerated combat audio has made it a favorite source for gaming memes, kill compilations and soundboard clips shared on Discord and YouTube. Creators keep using this particular groan because it instantly communicates massive damage in a way smaller hit sounds cannot.
