Ultrakill is a fast-paced retro first-person shooter developed by Arsi Patala and released in early access in 2020, known for stylish movement and heavy weapon feedback. Its large explosion effect became a staple in gameplay clips and fan edits because the blast is instantly recognisable and fits the game's relentless pace. Players share the clip outside the game as a standalone boom for memes and montages, where its short length and strong low end make it easy to drop over any sudden destruction or comedic failure.
