Great quality
Format: Hardcover
Not sure why the one guy had to compared this book the the MGSV one. But it is a great quality art book. Yes the paper is not glossy but it actually makes it more viewable in all conditions in my opinion. Paper very much reminded me of what high quality Japanese art is usually printed on. Love that the book comes with details on what they were thinking while designing everything. Great game worth the buy now before this thing becomes rare and hard to get!

Great Book, delivery could be improved.
Format: Hardcover
Overall, a great gift for a lover of this game. The content is beautiful. The only thing that was frustrating was our first order of the book was damaged, we had to get it replaced.

Gorgeous artwork in a beautifully bound book
Format: Hardcover
This was such a wonderful surprise! I cannot believe how beautifully bound this is, and the slipcase feels expensive too! It's a steal at this price point. The images are printed so nicely too, a lot of love went into this.

Halo Fan Must-Have
Format: Hardcover, Format: Hardcover
Stunning!! So much information and beautiful artwork. Must have for any Halo fan. This book is MASSIVE! Not so much a game guide, no level maps or multiplayer/campaign stuff. Lots of history about the war, colonies, Covenant, Flood, Banished, etc. Can’t wait to read it
