The walkthrough section deals mainly with the 10 storylines. Pointers and hints are given at tricky areas in the game; the determinant in your path options are also highlighted. Screenshots accompany each paragraph that teaches you the tricks of the trade. Tables are used to further illustrate the game's mechanics and enchances the over all usefulness of the guide.
Pandora's box no longer contains any secret once you get hold of this encyclopedia for PDO. Learn how to unlock 12 sub scenerios. Lots of CGs are unlockable, not just from this game, from the previous incarnations of Panzer Dragoons as well, mostly the introduction and ending CGs. Conditons that must be fulfilled for each extra to unveil itself are explicitly expressed in this gem. However, the S rankings walkthrough for sub scenerios and mini games are lacking. The criteria is there but you need to devise a strategy to achieve S rank yourself.
To sum it up, this is one of Prima's better efforts at putting together a superb guide.
