Dead by Daylight is an asymmetrical horror game released in 2016 by Behaviour Interactive, where four survivors face one killer. Skill checks are a core mechanic introduced to keep routine actions risky, appearing randomly during generator repairs and healing to test reflexes. The distinctive cue became instantly recognisable to players and spread into streams, memes and edits as shorthand for pressure and an impending fail. Its short length and clear meaning make it a staple sound for gaming creators recreating that in game anxiety.
