The Order: 1886 Signature Series Strategy Guide is going to provide a complete walkthrough for all the missions in the videogame. To do so, it will include exclusive maps of London to highlight the important locations and collectibles. There are also sections dedicated to the armory (featuring info on the armor, gadgets and weapon) as well as the bestiary. Last but not least, a free e-Guide (with updated content) is also packed in.
The official strategy guide is releasing on the 20th of February, the same launch day as The Order: 1886. The new I.P. is a third-person shooter from Ready at Dawn, the same developers behind the two portable God of War experiences.
