Avenge of Proitzen, a sort of "3.5" book that came out with the Zoid Core Box before OFB4 was released has also been added to the Official Fan Books page! The story segment is more or less the same as OFB4 so has been excluded from the book's page. The additional images can be found at the start, and all remaining book content (the fact files for Helic, Guylos, and Zenebas Zoids) has already been posted. This includes basic stats and descriptions for kits that didn't get to get profiles in OFB4, such as some of the Yuji Kaida Zoids and some of the customized model kits.
From here it's finally time to move on to the Zoids Battle Story books, which many of you will know better as the "OJR" Battle Story! Work on this is already underway, and there'll be another news post once a solid update / section is prepared for it.
