Dead by Daylight is an online asymmetric multiplayer survival horror video game developed and published 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;[a] the Killer must hunt and 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. The game was released for Windows in 2016,[3] for PlayStation 4 and Xbox One in 2017,[4][5][6] for Switch in 2019, and for Android, iOS, PlayStation 5, Stadia, and Xbox Series X/S in 2020.[7] It became Steam Deck Verified[b] in 2023.[8] Swedish studio Starbreeze Studios published the game on behalf of Behaviour from 2016 until 2018, when Behaviour bought the publishing rights.[9][10] Italian company 505 Games publishes the Nintendo Switch version, while Austrian company Deep Silver publishes physical copies for the PlayStation 5 and Xbox Series X/S versions. Dead by Daylight received mixed reviews upon release, but was a commercial success; it has since attracted more than 60 million players and improved its ratings.
