Famous Call of Duty leaker on Twitter @ZestyCODLeaks back in April regarding "x2" files data mined for an unknown event at the time. ZestyCODLeaks and those reading the leak figured it would be something big, seeing as when Black Ops Cold War was revealed, the data mined files read "x1."
Any type of news relating to Call of Duty: Vanguard has still been pretty scant, as there was no word on Sledgehammer's new title at the most recent E3.
Despite the lack of substantial and confirmed news on the game, fans remain hopeful through the avenue of Vanguard leaks that many got their hands on back in early June.
As November comes closer, more concrete content about Vanguard will come about.
