Kotaku - Still aching to scratch that FPS itch at school, work, on the bus, or anywhere that isn't home? And not with virtual controls? Sony's handheld Vita, with its twin analog sticks, should have been the device to scratch that itch. Sadly, though, the handheld has been light on first person shooters even after six months on the market. Activision aims to change that with Call of Duty: Black Ops Declassified, a Vita-only version of the most popular FPS around, Call of Duty. The game was unveiled with a gameplay trailer yesterday at Sony's Gamescom press conference, and I got to see more of it at the show afterward.
