Swordsmachine is an enemy from Ultrakill, the fast-paced indie shooter by Arsi "Hakita" Patala and New Blood. Short enemy sounds from the game spread through gameplay clips, boss edits and meme compilations because they are punchy and easy to time with hits. This particular pain sound is used by players who want a recognizable Ultrakill audio cue for damage, interruption or defeat. It stays popular because the game has a strong online fanbase and its combat audio is highly distinctive.
