Now, with that out of the way, we can tell you that this is also really weird. Like, Snake laying on a guy and choking him to sleep before he climbs into a barrel and spins so much he pukes, for example. There's other stuff too, but we don't want to ruin it for you. Just don't say we didn't warn you.
[Update: We've swapped out the video with something a bit more reliable. For fanatics, be sure to check out GameTrailer's HD version as well!]
