The Black Watchmen is an augmented reality puzzle game. The project can also be classified as an ARPG. There are no saves in it. The gameplay goes beyond the game itself. That is, from time to time gamers will have to minimize the program, launch the browser and start Googling terms and visiting sites that were created by the developers of a special project for this project. The creators also came up with articles and quotes from the books and then posted them online as well.

In the story, users work for the Black Guardians organization. This is the name of a group of people that protects ordinary people from paranormal phenomena, conducting rituals of occultists and secret societies. And users are assigned the role of agents – special detectives and hackers who investigate mystical cases. They are not told the identities of the clients, but only explained how to distinguish friend from foe and given a general briefing on a specific task.

There is training available, which helps you get used to the basic mechanics. The game is divided into seasons. It has dozens of missions and hundreds of puzzles. There are MMO elements. Sometimes players will have to interact with each other via the Internet and exchange links. The game also periodically hosts various events. The gameplay itself is based on searching for information, deciphering codes, analyzing the data received, comparing facts, and hacking the virtual defense of opponents.
