'Black Ops 4' is the first truly new Call of Duty game since 2007. It's refreshing.

For 11 years, Call of Duty has been a safe bet for Activision.  It's popular, it sells by the boatload, and it changes very little year after year. It prints money, basically. But Black Ops 4, released on Oct. 12, upends that common thinking. It's still safe — there's a freaking battle royale mode! — but it's not the Call of Duty many of us know. Think back to 2007. That's the year Call of Duty went from cinematic first-person shooter set during World War II — like so many other popular shooters at that time — to game-changer.
