If you look below, you will see a new trailer for Hitman: Absolution. It looks to be all pre-rendered, but given what has been shown before, a little bit could be in game. Doubtful, but there could be a chance. Anyways, that is not what I want to bring to your attentions. If you look past all of that, you can see a schooner very well snuck in slap at Assassin's Creed. At least this is how I am taking it and so should you. Because I said so. There might be punch and pie.
During the final scenes of the trailer the phrase "The Original Assassin" flashes on screen. Something that can and might be passed off, but I see that as a snide placement about how Hitman's #47 was killing people in secret for 7 years before Altaïr was sneaking through locales of yore. As I said, I am one who enjoys these kinds of things even if it is my own little mental invention and nothing meant at all by Square.
Either way, enjoy the new footage of Hitman: Absolution.
