Over all expectations
This book covers real secrets for veterans, awesome design, top of all the guides I ever had.

After finishing the game, it sumarizes all the experience for you, history of characters in MGS series and so on.

A Must-Have MGS4 Book!
If you want to fully utilize your MGS4 experience, then buy this!

You have to finish the game first before fully reading it if you don't want spoilers. :D

The MGO Guide is very nice as well!

Best MGS4 stuff ever!!!
This guide is awesome! Specially if you are a true fan of the MGS series. Kojima productions really put some effort on making this one. Everything about MGS4 is here! maps, weapons, boss fights, secrets, easter eggs, biographies... everything!

The guide also have a section of original Shinkawa's artworks! 16 pages of pure solid snake's original sketchs!

Also, If you're looking ofr detailed explanations about the series' plot and history, i'll find it here. There is a lot of information on this apsect.

Well, a "ten stars" MGS4 guide. That's all there is to say.

AWESOME!!
A great book, every detail of the game is included even MGO details. Too much Spoilers, but you just can't help to read everything in it!
