Call of Duty: World at War is a 2008 first-person shooter game developed by Treyarch and published by Activision. It is the fifth main installment of the Call of Duty series and is the fourth entry in the series to be set during World War II.

Call of Duty (COD) is a video game series started in the early 2000s. The first 6 games are about World War II, but the series began branching out beginning with Modern Warfare. The series now spans World War II, the Cold War, the present, the near future, and the far future.

Yes, Black Ops 3 is still active on Xbox One. Despite being released in 2024, the game continues to have an active player base on the Xbox One platform.

Black Ops 4, however, is basically "re-skin" of Black Ops III (for multiplayer) as there are almost no differences. Black Ops 4 only had fourteen multiplayer maps at launch with four of them being remastered versions of maps from previous games.
