A New Digimon Story: Cyber Sleuth Title Appears!

For the March 2015-released Digimon Story: Cyber Sleuth, the basic concept of the Digimon Story series so far—a training RPG where you “adventure,” “train,” and “battle” while collecting Digimon—was kept in tact, and by powering up the setting and game systems with the theme of being a “game directed towards adults,” the title received high praise from many Digimon fans.

Digimon Story: Cyber Sleuth Hacker’s Memory will be a new entry in the Cyber Sleuth series based on the setting and game systems of the previous title, in which a new story will develop.
A Story on the Other Side of “Cyber Sleuth”

Digimon Story: Cyber Sleuth Hacker’s Memory will tell another story that happened on the other side of the
events depicted in Digimon Story: Cyber Sleuth, from the point of view of a new protagonist.

In near future Tokyo, where the boundaries between reality and cyberspace have blurred, players will use AI-based computer viruses known as “Digimon” generated in cyberspace and become a new generation of hacker to solve the case of a rise in hostile hackers and Digimon.

The protagonist is not a hero chosen to save the world.
In the face of a world crisis—while previously established common sense and values significantly change—struggle to desperately protect your friends, family, and the place where you belong. This is a cyberpunk story with even stronger sci-fi elements!

Digimon Story: Cyber Sleuth Hacker’s Memory depicts the story that happens on the other side of the previous title from the point of view of a new protagonist and characters.

The scenarios and quests are brand new and have the same volume of the previous title, the total number of Digimon that will appear has become 320, and the breadth of training has expanded.

Also, since it is set in the same world, it will share maps with the previous game, but about 30 new maps have been added for a total of about 90 maps.
