A downloadable expansion for Sleeping Dogs, Nightmare in North Point was developed by United Front Games and released in 2012 for PlayStation 3, Xbox 360, and PC, with later availability on PlayStation 4 and Xbox One. The add-on transforms the base game's open-world Hong Kong setting into a supernatural horror scenario in which protagonist Wei Shen pursues the kidnappers of his girlfriend through a city overrun by hopping vampires, demons, and vengeful ghosts. The content builds directly on Sleeping Dogs' action-adventure combat framework while introducing new moves and weapons tailored to confronting these paranormal threats. The expansion blends the series' grounded crime-thriller foundation with classic Chinese folklore horror imagery, offering an experience distinct in tone from the main campaign while retaining the core brawling and open-world traversal mechanics that define the franchise.
