It looks like the upcoming Final Fantasy Type-0 HD is going to get an official strategy guide. Amazon has out up a listing for the Final Fantasy Type-0 HD: Prima Official Game Guide with a release date set for the 17th of March in 2015. It has a ISBN-10 of 110189847X and ISBN-13 of 978-1101898475. You can preorder the book right now with this link on Amazon.
Only the hardcover version has been listed so far. Prima Games usually release a cheaper paperback iteration as well for most major strategy guides.
Final Fantasy Type-0 actually came out in 2011 on the PSP. However, it was never translated into English until now. Square Enix went with the PlayStation 4 and Xbox One so that they can build the user bases of the two current-gen consoles before the release of Final Fantasy XV, which should be occurring sometime down the road.
Speaking of Final Fantasy XV, a playable demo is being added to all collector’s edition copies of Final Fantasy Type-0 HD. It is also included in first-print runs of the regular versions of the port. If you haven’t already, you can preorder the HD release of Final Fantasy Type-0 with this link on Amazon.
