Ultrakill is a retro first-person shooter developed by Arsi Patala and published by New Blood Interactive, released in early access in 2020. Its high-speed combat, ranking system and distinctive audio cues made short clips from the game popular on soundboards and in fan edits. Players share individual effects out of context so they can be reused as reactions, which is how brief cues like this one spread beyond gameplay into memes, streams and short-form video, long after the original moment has passed.
