Call of Duty: Ghosts - expected to be this year's Call of Duty title - has been outed by UK retailer Tesco.
The retailer listed the game for Xbox 360 and PS3 this afternoon, along with the alleged box art. It has since pulled both listings, however.
Infinity Ward's logo is featured prominently on the box art, suggesting the Modern Warfare developer is back for Ghosts, and also appears to show a character putting on the mask worn by Ghost in Modern Warfare 2.
Call of Duty: Ghosts has previously been rumoured to be the name of this year's Call of Duty.
Earlier this year, YouTuber Drift0r claimed that he had been supplied information about Call of Duty: Ghosts from a "very legitimate source", alleging that the game could be "branching out of the Modern Warfare series" and "moving into a different direction".
The title is rumoured to be set in the future similar to last year's Call of Duty: Black Ops 2, but uses current generation weaponry.
Activision has yet to formally reveal this year's Call of Duty title, but an announcement, Drift0r states, is expected around May 1, 2013.
An Activision representative gave VideoGamer.com a "no comment" when contacted about the leak.
