Metal Gear Solid 4 Playable Demo - Video

Last Christmas I wrote a few posts that alluded to Metal Gear Solid 4. I referred to MGS4 very fondly and said it was the sole reason I was looking forward to acquiring a Playstation 3.

I posted a link to some Metal Gear Solid 4 cinematic trailers that blew me away. But now, a playable demo is circulating the net and it's equally impressive if not more so. The war sequences are so realistic (like I've ever been in a firefight, right? Well, it's very realistic as compared to war movies that I've seen or as what I imagine what war is like.)

Here is a direct link to the video.
If you have 15 minutes of free time, watch it. It's awesome.

Below are the (lower quality) YouTube versions of the same movie.
