C'mon, you know we've gotta have a thread for this. :)
While we wait for the complete trailer (which, at this point, is rumored to be anywhere from nine to fifteen minutes in length), I will say this about the teaser version: Raiden is scaring the hell outta me now.
And is it just me, or is Ocelot bearing a striking resemblance to The Sorrow now? I wonder if that was a conscious design choice?
