This is a damn fine series!
Sangmin Bang, you worked incredibly hard on this; and it has paid off. First of all, the animation is excellent for something like this. I have yet to see something top this that isn't Combat Instinct related. Second, the sound is perfect this time and it shows. Rather than use the mediocre voice cast of the previous episodes; you decided to use the Korean voice cast with English subtitles. Not to mention that the music and sound effects fit.
What I did like:
-Great Voice Acting
-Great Animation
-Quality Storytelling
-Excellent Character Designs
What I didn't like:
-The Man vs. Machine thing is cliched, but at least you made it work.
Overall: You are proof that South Korea can make its own animated stories, rather than animate Western fare. Therefore, Gunchest 03-1 deserves a ten for just kicking ass.
