Amazon has listed some details for the two versions of the Assassin’s Creed Syndicate Official Strategy Guide. If you are interested, you can preorder either iterations with the following links from the online retailer: Assassin’s Creed Syndicate Official Collector’s Edition Guide and Assassin’s Creed Syndicate Official Strategy Guide: Standard Edition. Check out the covers of the two Prima Games guides below this paragraph. 
Both guides will provide a complete walkthrough of the open-world action-adventure game. Among the subjects that are being covered include tips of using every skill to its fullest potential in addition to learning about all the gangs roaming the streets of London. Of course, detailed maps are included as well. In addition to the physical book, a code to download the digital eGuide version will be added to the products.
Exclusive to the collector’s edition are a premium hardcover, full-sized world map poster featuring the aforementioned London game world in addition to a bonus DLC weapon called the Angel Knuckles (which allows you to attack enemies from above). The collector’s edition of the guide will only be printed once.
The Assassin’s Creed Syndicate Official Strategy Guides are coming out on the same day as the videogame, which is being released on October 23rd on the PlayStation 4 and Xbox One (the PC version is coming out later in 2015).
