Dead by Daylight is an asymmetric multiplayer survival horror online game developed by Canadian studio Behaviour Interactive. It is a one-versus-four game in which one player takes on the role of a Killer and the other four play as Survivors; the Killer must impale each Survivor on sacrificial hooks to appease a malevolent force known as the Entity, while the Survivors have to avoid being caught and power up the exit gates by working together to fix five generators. Alongside original characters, the game licenses characters and settings from franchises such as A Nightmare on Elm Street, Attack on Titan, Crypt TV, Evil Dead, Halloween, Hellraiser, Left 4 Dead, Resident Evil, Ringu, Saw, Silent Hill, Stranger Things, and The Texas Chainsaw Massacre. The game received mixed reviews upon release, though it was a commercial success and has since attracted more than 50 million players. A film adaptation is currently in development by Blumhouse Productions and Atomic Monster Productions.
