On Twitter, Victor_Z, who previously leaked correct information about Call of Duty: Black Ops Cold War, posted a photo of Call of Duty: WW2, which was developed by Sledgehammer Games.
He added a hammer emoji to the message, appearing to suggest the studio is working on a new Call of Duty game. Earlier there were rumors that Sledgehammer is making the still unannounced Call of Duty game for this year.
When a Twitter user asked if it was World War III, Victor_Z announced that the game is set around World War II.
As yet nothing is known about the new Call of Duty game due to be released this fall, except that the game is in the works.
