R.E.P.O. is a co-op horror extraction game released in early access in 2025 by Swedish studio Semiwork. Players explore haunted locations to recover valuables while avoiding monsters that react to sound and movement. The Hunter became a fan favourite enemy because its blindness makes voice chat and accidental noises genuinely risky. Clips of Hunter encounters spread quickly on TikTok and YouTube in 2025, and short audio cuts from those moments began circulating as reaction sounds for gaming edits and streams.
