Metal Gear!? It can't be!
This is the NES port of the first entry in the ever-popular Metal Gear series, created by Hideo Kojima and developed and published by Konami; there are significant differences between it and the original MSX version (http://tasvideos.org/2974M.html). It is infamous for its engrish (http://www.engrish.com/), containing such ever-popular phrases as "I FEEL ASLEEP!" and "UH - OH! THE TRUCK HAVE STARTED TO MOVE!".
This run utilizes quite a wide variety of game glitches and collects the minimal set of items needed to complete the game. Additionally, this movie improves the previous movie (http://tasvideos.org/3233M.html) by 2 frames.
