God of War Ragnarök is an action-adventure game developed by Santa Monica Studio and published by Sony Interactive Entertainment. It was released worldwide on November 9, 2022, for both the PlayStation 4 and PlayStation 5, marking the first cross-gen release in the God of War series. It is the ninth installment in the series, the ninth chronologically, and the sequel to 2018's God of War. Loosely based on Norse mythology, the game is set in ancient Scandinavia and features series protagonist, Kratos, and his now teenage son, Atreus. Concluding the Norse era of the series, the game covers Ragnarök, the eschatological event which is central to Norse mythology and was foretold to happen in the previous game after Kratos killed the Aesir god Baldur. The gameplay is similar to the previous 2018 installment. It features combo-based combat, as well as puzzle and role-playing elements. The gameplay has been revamped from the previous game: in addition to Kratos' main weapons, a magical battle axe and his double-chained blades, he also acquires a magical spear and his shield has become more versatile, with different types of shields that have differing offensive and defensive abilities. His son Atreus, as well as some other characters, provide assistance in combat and can be passively controlled. Additionally, and for the first time in the series, there are some story missions where the player takes full control of Atreus; his gameplay is similar to Kratos, but he uses his magical bow as his weapon. There are also more enemy types and mini-bosses than in the previous game. Originally slated for a 2021 release, the game was delayed in part due to Kratos actor Christopher Judge's health problems in August 2019, and later, the impact of the COVID-19 pandemic on development. A free downloadable content pack titled Valhalla was released on December 12, 2023, and serves as an epilogue to Ragnarök, following Kratos and companion Mímir in a series of trials within Valhalla in order for Kratos to come to terms with his past life in Greece. Ragnarök garnered universal acclaim from critics and was praised for its storytelling, characters, visuals, level design, music, and overall improvements to the gameplay over its predecessor. The game sold 5.1 million units in its first week, making it the fastest-selling first-party launch week in PlayStation history, with over 15 million units sold as of November 2023. At The Game Awards 2022, Ragnarök received a leading 11 nominations, including Game of the Year, winning six. It received a leading 12 nominations at the 26th Annual D.I.C.E. Awards, ultimately winning seven awards including Adventure Game of the Year. It received a leading 15 nominations at the 19th British Academy Games Awards, the most nominations for any game in the history of the ceremony, from which it won six awards, including the EE Game of the Year Award.
