Heading over to the official Call of Duty website, players are now able to log in to their Call of Duty account, and it is linkable to Blizzard's Battle.net, for PC users.
The video was posted on the YouTube channel of Call of Duty and managed to collect almost 1.5 million views.
A press release that can be seen on Business Wire also confirmed that the aforementioned first-person shooter will be released for the PC, PlayStation 4 and Xbox One. This date indicates that the game will be out more than a month sooner than the expected date.
While it would make sense that Black Ops 2 - still hugely popular with fans - would be the project being released this year, there's always the possibility of MW2 Remastered being included instead.
Despite the fact that the Network appeared information about the release of Black Ops 4 Switch on the Nintendo, Activision has not yet made any comment about it.
As for the details that have been revealed for the game itself, Activision hasn't revealed too much on the game just yet aside from noting that it'll be set in the "near-future", a detail that may indicate some similarities to features and mechanic found in Call of Duty: Black Ops 3.
However, self-proclaimed "industry insider" Marcu Sellars, who seems to have been the first to leak news about "Black Ops 4", tweeted that there is already a company working on making the game compatible with Switch. It is set in the modern times and is boots on the ground.
The game will be released for PS4, Xbox One and PC and it will be out on Friday, October 12th.
