Interesting approach, we haven't had too many books reviewed here at the site. Thanks for branching out adn trying something new.
It's a good start to a book review, I think. It could use a bit of fleshing out. I'd add a bit more background for those of us who've never played Halo. (Yes, it's true, we exist!

)
I did like your detail about how the realistic discussion of weapon background added to your enjoyment. I'd like to see more about the plot or character development (without spoilers), and what happens that makes me want to read the story. Or what it means to be SPARTAN, and the significance of Master Chief. (Yeah he's the star of Halo... but what is significant about that, if anything?)
Thanks for writin'.
