With the return of classic round-based zombies inCall of Duty: Black Ops 6, you and your friends can dive into the familiar thrill of zombies mode once more. It’s a well-crafted experience that does justice to the series. If you’ve tried zombies mode in previous COD games, you already know the maps are packed with hidden Easter eggs to uncover.
