About Witch

The Witch is a fictional monster in the Left 4 Dead series of video games. She is a particularly powerful zombie in the game, but unless agitated, will not attack the players. She is usually seen crying while sitting, and if approached or bothered by light or sounds, will become more agitated. She chases the agitating character to kill them, fleeing once she succeeds. She also appears in Left 4 Dead 2, gaining a new form during the day that is able to wander around with her eyes covered. When a Witch is present, her crying and a music theme consisting of wailing moans and piano notes can be heard. Left 4 Dead writer Chet Faliszek stated that this was a simpler way to convey "scary, threatening, and cool" despite discouraging players from approaching her.
