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 savage Killer and the other four play as Survivors; the Killer must catch each Survivor and sacrifice them to a malevolent force known as the Entity by impaling them on hooks, while the Survivors must avoid being caught and fix five generators to power up the exit gates. The game was released for Windows in 2016; PlayStation 4 and Xbox One in 2017; Switch in 2019; and Android, iOS, PlayStation 5, Stadia, and Xbox Series X/S in 2020.
Swedish studio Starbreeze Studios published the game from 2016 to 2018, and it has since been published by Behaviour Interactive. Italian company 505 Games publishes the Nintendo Switch version, while Austrian company Deep Silver publishes the physical copies of the PlayStation 5 and Xbox Series X/S versions.
Alongside original characters, the game includes characters and settings from various franchises such as A Nightmare on Elm Street, Attack on Titan, Crypt TV, Evil Dead, Halloween, Hellraiser, Left 4 Dead, Resident Evil, Ringu, Saw, Scream, Silent Hill, Stranger Things, and The Texas Chainsaw Massacre. The game received mixed reviews upon release, though it was a commercial success and has attracted more than 50 million players.
