It's actually pretty decent, I'm kind of surprised..
I'm not really into FPS games, nor do I have that much knowledge regarding firearms, so I wouldn't be able to tell If the MC's weapon choices and, or fighting style make sense or not, therefore It doesn't really bother me.
ignorance is a bliss, I guess LOL
My only complaint is the pacing of the story, "So many chapters, so little development" is a understatement here. IT IS SO FREAKING SLOW!!! D:
I hope we get more chapters soon. :c
