Ultrakill is an indie first-person shooter developed by Arsi Patala and published by New Blood Interactive, first released in early access in 2020 and praised for its fast, retro-inspired combat. Its punchy, exaggerated sound design became a favourite among players who clip and share gameplay moments, and individual impacts like this one were lifted from play sessions for use in edits. Because the hit is short, loud and instantly readable, it travels well beyond Ultrakill videos, giving any fight, meme or montage a satisfying sense of force.
