Dead by Daylight is the asymmetrical horror game released by Behaviour Interactive in 2016, where one killer hunts four survivors. Its trial start sting became part of the game's identity because players hear it at the exact moment a match loads in, before repairing generators or being chased. As the game grew on Twitch and YouTube, the short cue spread beyond gameplay into edits and memes as shorthand for something frightening about to begin, even for viewers who have never played a match themselves.
