Nihilistic Software has revealed a few more details about its upcoming Call of Duty entry on the PlayStation Vita, Black Ops: Declassified.

Head of Nihilistic, Robert Huebner told the PlayStation Blog about one of the game’s maps known as Nukehouse, which oddly enough is inspired by Black Ops‘ Nuketown. “Nuketown is obviously a fan favorite so we wanted to really do a homage to that map,” he said. “Nukehouse is a tighter level overall but tries to capture the unique look and feel of the original.”

He also mentioned that 12 perks will be available to players, “Hardline, Marksman, Sleight of Hand, and Lightweight are all back, but new perks like Surplus (extra starting ammo and grenades), Hardwired (immune to Counter Spy Plane) and Toughness (reduced flinching when shot) are also important to remember when creating classes.”

Finally Huebner offered up some details regarding the game’s single-player, “The single-player campaign consists of intense and replayable objective-based missions that allow you to get better and better over time to improve your performance. The goal is to give the player the experience of striving for the ‘perfect run’ through each mission.”

“Hostiles” missions as we call them now are the classic ‘survive infinite waves’ sort of challenge. The player has to survive wave after wave of different enemy types, but also receives “care package” drops during play to keep them supplied.”
