Call of Duty's Vita debut was a bit scant on details. Call of Duty: Black Ops Declassified was announced at Sony's E3 press conference with a logo... and not much else. While Activision has yet to show off any official media of the game, retailers have given us a better understanding of what to expect from the handheld spinoff.
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.
Based on the description, it appears Declassified will not jump into the future like Black Ops 2 for console. It also appears there won't be a story mode in the traditional sense. Instead, the campaign seems to be comprised of Spec Ops missions. As IGN points out, its "on-the-go" nature may make it similar to Zipper Interactive's Unit 13, which featured bite-sized missions and a focus on leaderboards.
The Vita version will also feature multiplayer--a key feature for the Call of Duty series. However, because it is "tailored for the PS Vita," don't expect any cross-play features with the PS3 version.
