A description for the PlayStation Vita shooter appeared earlier today on Walmart's website, including hints at the game's story and multiplayer modes.
The Walmart listing is as follows: "Before the future could be won, history had to be written. Exposing that story exclusively on PlayStation Vita, Call of Duty: Black Ops Declassified explores original fiction in the Call of Duty Black Ops universe with an all-new campaign of Special Ops missions.
"Optimized for gamers on-the-go, Call of Duty Black Ops: Declassified delivers the most intense handheld Call of Duty experience to date, including both Special Ops Story mode and Multiplayer combat tailored for the PS Vita."
In the Call of Duty series, Special Ops is the name given to the game's co-operative multiplayer missions. This could suggest that the story mode in Call of Duty Black Ops: Declassified will be similar to those missions and feature co-operative support, though it is unconfirmed at this time.
Walmart has since removed the description from its website, though it can still be seen through a Google cached version of the page.
Sony announced Call of Duty Black Ops: Declassified for PlayStation Vita during its E3 press conference, with no additional details given beyond its name.
Treyarch is also working on Call of Duty: Black Ops 2, which is set during a 21st century Cold War and will release on November 13 on Xbox 360, PS3 and PC.
Call of Duty Black Ops: Declassified will release on PS Vita during the "holiday season".
