Middle East Ground Zero. All the cut scenes with little bits of gameplay thrown in. I'm playing at the Boss Extreme difficulty level. I will attempt to get a 'no alerts' , 'no recovery items used' and 'no continues' game completion. I will not be going for the Big Boss Emblem because that would mean cutting all the movies out of the walkthroughs.
There is a special edit in there which all you true Metal Gear Fans will appreciate. Enjoy.
