Ultrakill is a fast-paced first-person shooter released in early access in 2020, built around aggressive movement and close-range combat where bathing in enemies' blood restores health. That makes splatter sounds a constant part of its audio design, rather than a rare effect. Clips from the game spread through gameplay videos, montages and short-form edits, and creators began lifting individual impact sounds for their own projects. This variant remains popular because it is short, recognisable to fans and instantly signals a messy Ultrakill-style kill.
