Ultrakill is a fast-paced retro FPS developed by Arsi Patala and published by New Blood Interactive, first released in early access in 2020. Gabriel, an archangel and major boss, became one of its most quoted characters thanks to his intense voice acting and dramatic boss encounters. Short clips of his lines spread widely through gaming communities, Discord servers and soundboards, where they are reused far outside the original fight as reaction sounds and editing punchlines.
