When Call of Duty: Vanguard releases later this year, the game will bring back the Castle and Dome maps from Call of Duty: World at War. The news was revealed in a new blog post from developer Sledgehammer Games, and should be welcome news for longtime fans of the series. These are two maps that haven't appeared in a Call of Duty game in quite some time, and they'll be getting a number of changes from their initial appearance in World at War. Notably, players can expect to see reactive environments, offering a significant difference from the maps that debuted back in 2008.
