Call of Duty: Black Ops Cold War has been updated to version 1.27 today by Treyarch. You can find out the complete patch notes from here.
The biggest change is perhaps the ability to view all the season challenges now. If you haven’t completed any of the previous season’s challenges, you have the time to do it after installing this new update. You can find out the complete patch notes below, or take a look at the official website.
