Oh ... dear. This is exactly the sort of video the internet shouldn't be showing us. Does it not realize the colossal, sensory danger posed by a combination of two of our favorite franchises? Seeing the Assassin's Creed garb running around a modern environment is one thing, but when the mise en scène happens to feature Metal Gear Solid 4 gameplay, we stop asking questions ("Where did this come from? Why is it so unrelenting in its awesomeness?") and start experiencing debilitating gleezures. That's glee + seizure, FYI.
