The next 'Call of Duty' game, codenamed 'Saturn' and referred to as Call of Duty 2025, is a semi-futuristic sequel to 'Call of Duty: Black Ops 2'. The game is in early development, with a release anticipated around 2030. It will feature new and remastered maps, an overhauled movement system, and the potential return of popular features from previous games. Microsoft's Activision Blizzard has shifted plans from initially including remastered maps from Black Ops 2 to a mix of new and remastered content. The game aims to balance novelty with nostalgia, building on the success of Black Ops 2.
