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. Canβt wait to read it
