ULTRAKILL is a retro-styled first-person shooter developed by Arsi 'Hakita' Patala and published by New Blood Interactive, released in early access in 2020. The Streetcleaner is one of its enemy machines, a flamethrower-wielding robot players encounter as they descend through the layers of Hell. Clips of its distinctive mechanical noises circulate online among the game's fan community, where they appear in memes, highlight reels and speedrun edits. The game remains in active development with a dedicated following, keeping its enemy sounds popular years after release.
