Metal Gear Solid V Ground Zeroes - Ground Zeroes S Rank Walkthrough

I was playing Metal Gear Solid V: Ground Zeroes earlier tonight and found that I was a little bit rusty at being covert and sneaky. I felt a little defeated in trying to live up to the Legendary Snake's name. Plus I was also limiting my chance a decent trophy whore run. There are only 15 in this game and I want to be able to grab all of them, making this my second game to achieve platinum trophy status. I gotta say though the AI in this game is a bit more intuitive than the others. The thing I like about this game though is if you get caught you have that split second moment to subdue the enemy before they have a change to alert the others. 

Luckily I was searching through YouTube and I came across, a guy named Maka, Maka91Productions, his video walkthrough for an S ranking. He made it seem so easy. While I was a bit more cautious and pretentious in my run, he was more fluid, decisive, and exact. Of course this was only my second run through of the game where he had basically speed runs under his belt. I'm gonna go back into the game and knock it out now like I know I can with some balls of steel and grit just like the Legendary Big Boss would. Take a look at the video.
