Well, we called it - though I daresay you did too. It turns out that last week's MGS Rising: Revengeance teaser was indeed for a full-length live action trailer, which purports to be footage taken from Raiden's severed arm. Expect lots of shaky camera footage, fast cuts and evil doctors. Konami plan to release another one when this video does the rounds, so we'll keep you posted.
For my money, the latest gameplay trailer does much more justice to Platinum Games' objective: to inject Metal Gear with their trademark brand of insane, ridiculous action. Either way, we've got the new trailer below, and we'll see what the creators of Bayonetta and Vanquish can towards the end of the year.
