Dead by Daylight is an asymmetric survival horror video game developed by Behaviour Interactive.Dead by Daylight was released for Microsoft Windows in June 2016, released in PlayStation 4 and Xbox One in June 2017, released in Nintendo Switch on September 24, 2019, and a mobile port on iOS and Android on April 17, 2020. The Stadia version was released in October 2020. The PlayStation 5 and Xbox Series X/S versions is released on November 2020. The game is played as a one-versus-four online multiplayer where one player takes on the role of a savage killer and the other four play as survivors trying to escape the killer and avoid being caught and sacrificed to a malevolent force known as the Entity.

A group of four survivors must elude one killer bent on sacrificing them on hooks to "The Entity", an almighty malevolent being. The survivors' perspectives are third-person, while the killer's perspective is first-person. The survivors can only fight back by stunning the killer or using items such as flashlights to blind the killer. Survivors can also vault over obstacles much faster than the killer, therefore providing a means of escape. Survivors use these obstacles and tools to help them elude the killer for as long as they can.

In order to escape, survivors must repair five generators scattered across the map to power up the exit gates. They must then open the exit gates and leave the area, or find an escape hatch to jump into. Repairing can be made quicker with items such as toolboxes.

Alongside original characters, the game also includes characters from various horror franchises such as Halloween, Left 4 Dead, The Texas Chainsaw Massacre, A Nightmare on Elm Street, Saw, Evil Dead, Fun World's Ghost Face, Stranger Things, Silent Hill, Crypt TV, Resident Evil, and Hellraiser. As of January 1, 2018, Behaviour Interactive became the game's publisher, acquiring publishing rights from Starbreeze Studios
