You don’t really expect that you will get much good gameplay from Call of Duty: Black Ops Declassified on the PS Vita, but you might be surprised at just how short the single-player campaign actually is.
PocketGamer, in their review, says that the single player campaign can be completed in just 45 minutes, which is really really lame even for a handheld console. I mean the game costs $49.99. The campaign is ten missions and apparently they can be completed in three to four minutes each. Other reviews say the same.
The console and PC version single player gameplay lasts around six hours, but if Declassified can be finished in under an hour, it makes it one of the shortest retail games ever released and that begs the question: Why? Why do they think they can stick it to PS Vita gamers like this? And does it say something about how little they think of gamers on that platform? Maybe they are used to gamers paying for anything and taking it, but this is ridiculous.
