The first page details about the protagonist and how he fits into the story. "Keisuke Amazawa falls victim of identity theft and is accused of a crime he didn’t do. In order to find the culprit, he joins a team of hackers called “Hudie,” with a base of operations at a cyber café. With Hudie, you’ll take on various requests from the PC. From there, you’ll be required to take on dungeons, investigate the real world, and put your hacking skills to use."
The second page is all about the two main allies helping you, Erika Mishima "a genius hacker, a member of Hudie, a girl who is extremely shy of strangers, and a shut-in who lives together with her older brother. An incident in her past has awakened the genius in her. Her partner is the cowardly Wormmon. After Erika saved it from a pinch in the past, they’ve been partners ever since. The two will work together with the protagonist and even help out in battles at times." And of course the other one is Fei, returning from Cyber Sleuth, a ruthless Zaxon hacker who uses Hudie to take out opposing forces.
The Digimon Story: Cyber Sleuth- Hacker's Memory Limited Edition "Digimon 20th Anniversary Box" will come with a number of extras...
1- It appears the version of the game included in the box is the "TV Animation Sound Edition Version" and includes a dozen songs from Digimon anime integrated into the game.
2- A Digimon Story Art Book
3- Hacker's Memory Soundtrack CD
4- A physical business card for the Kuremi Detective Agency that includes DLC codes for NXEdge Alphamon and Dukemon (oddly, unlike Omegamon, these do not seem to have the 'NX" appended to their names in the descriptions.)
5- A 20th Anniversary Box
So the Producer of "Digimon: Hacker's Memory" dropped a bombshell in a new interview that a new Digimon Story game is in the works that will apparently not be related to the Cyber Sleuth series. He said that part of the reason they made HM was because this new game is going to take a long time to make and HM was to tide us over.
