Call of Duty: WWII was a breath of fresh air after the weirdness what was Infinite Warfare. The return to historical battles was a welcome change after a (thankfully) brief trip to space. For 2018, the series is back in the hands of Treyarch, which means a new installment of Black Ops. The studio, along with publisher Activision, already took the wraps off the game a few weeks ago. Perhaps most importantly, the duo revealed that the single-player campaign would be replaced by a PUBG-esque battle royale mode. Of course, the popular CoD multiplayer isn't going anywhere, and that's what Activision is showing off at E3 this week.
