I was wondering the same thing today and I stumbled upon this today:
Vanquish Campaign Length Confirmed
October 18th, 2010
This month's Game Informer Magazine featured a review of Vanquish. In that review the editor's claimed the game's campaign could be beaten in less then 4 hours. Since this issue was released, there has been a lot of speculation as to how true this really is.
So much speculation in fact that Platinum Games themselves came out and commented on this by saying that, "GameInformer: 'Don't be surprised if you finish your first playthrough in four hours.' Really? Because it would surprise the hell out of us.", followed shortly by, "Even in Casual Auto it doesn't make sense, nor is it indicative of how long a normal gamer's playthrough would take.".
Well, thanks to user "IllISTGaMer" for sending this screenshot of his finished game. Take a look at the screenshot below to see just how long this game really is.

So there you have it. It's now confirmed. The game can easily be beaten in less than 4 hours on the first playthrough. What are you going to "Tweet" about on this one Platinum Games?
