Wolfenstein II: The New Colossus is a 2017 action-adventure first-person shooter video game developed by MachineGames and published by Bethesda Softworks. It was released on 27 October 2017 for Microsoft Windows, PlayStation 4, and Xbox One, and was released on 29 June 2018 for Nintendo Switch. The eighth main entry in the Wolfenstein series and the sequel to 2014's Wolfenstein: The New Order, the game is set in an alternate history which takes place in 1961 following the Nazi victory in the Second World War. The story follows war veteran William "B.J." Blazkowicz and his efforts to fight against the Nazi regime in the United States.

The game is played from a first-person perspective and most of its levels are navigated on foot. The story is arranged in chapters, which players complete in order to progress. A binary choice in the prologue alters the game's entire storyline; some characters and small plot points are replaced throughout the timelines. The game features a variety of weapons, most of which can be dual wielded. A cover system is also present. Continuing from The New Order, the development team aimed to characterize Blazkowicz for players to adopt his personality. Mick Gordon returned as the game's composer, and is joined by Martin Stig Andersen.
