Ultrakill is a fast-paced retro first-person shooter developed by Arsi Patala and released in early access in 2020 by New Blood Interactive. Its combat relies on constant movement and heavy weapon impacts, so its explosion sounds are deliberately exaggerated and bass-heavy. This bigger variant circulated through gameplay clips, edits and soundboards because it stands out even without visuals. Players and editors kept reusing it outside the game as a shorthand for massive damage, turning a specific in-game effect into a general meme blast for gaming videos.
