In GTFO, the cooperative horror shooter from 10 Chambers, scouts are sleeper enemies that patrol dark zones and shriek to wake nearby foes when disturbed. That alert sound comes from that in-game detection moment, where a single mistake can summon a whole horde. Clips of failed stealth runs and streamer reactions helped the screech travel beyond the game, shared on soundboards and reused in edits. It remains popular because it instantly signals danger, even for viewers who have never played GTFO.
