Digimon Story Cyber Sleuth: Hacker's Memory is a side story to Digimon Story Cyber Sleuth. It's essentially a behind-the-scenes look at some of the things that were happening during Cyber Sleuth. Here you play as a main character who's not exactly the main character type - he's more of a side character. Although it isn't necessary to have played Cyber Sleuth in order to enjoy this game, it will certainly make more sense if you have. Characters from Cyber Sleuth make cameos in Hacker's Memory, and the overall, arching plot of this game's world is best explained in Cyber Sleuth.
Combat is essentially the same as it was in Cyber Sleuth, but this time new battle modes known as 'domination battles' and 'territory capture battles' have been added. In addition, there is now a larger roster of Digimon for you to choose from.
*Note: If you have a saved data from Cyber Sleuth, you can actually transfer it over to Hacker's Memory. This will bring over any medals you have collected, your Digimon field guild, your play time, and give you a few free items to start with. If you've finished Cyber Sleuth, then this will help cut down on your play time. (Don't fear if you haven't, however, as everything can be done without it.)
For your first play through, you're going to want to play through the game and take note of the few things that are missable. There are no difficulty related trophies, so feel free to play on whatever difficulty you feel comfortable with. (This can be changed at anytime.) Spoilers have been kept to a minimum for the purposes of this guide. Only important notes have been added to each chapter's description, and anything heading into spoiler territory has been marked.
When entering a new area or dungeon, you're going to want to scour the map to find anything you can pick up. This will make clean-up at the end of the game much easier. You'll also want to be Digivolving and De-Digivolving as many Digimon as possible to help fill out your field guide. Until you get later in the game (ie. the offline coliseum) you don't have to worry too much about what Digimon you use, so feel free to use your favorites. (However, you'll want to start building up a solid team the further towards the end you get.)
Although side quests aren't required to advance the game, it is recommended that you complete them anyways. This will help you get a head start on your hacker rank. Some of these side quests also offer medals that are needed to complete your collection, and the domination side quests and territory side quests are necessary to see a character's impression events.
It's suggested that you finish up all (or at least most) trophies before heading into New Game+. While some things such as your medal collection will carry over, your hacker's memories and number of repaired Mr. Navits, will not. Therefore, you must get them all before starting New Game+. (Otherwise you'll be collecting them all again.)
To sum it up, you'll want to focus on the following for your first play through:
- Repairing all Mr. Navit's
- Finding all Hacker's Memories
- Registering 300 Digimon in the Field Guide (Making sure to specifically Digivolve a Hudiemon, Chaosmon, Chaosmon VA, and a Susanoomon)
- Collecting all 700 Medals
- Seeing all Good Impression events for a single human and Digimon character
- Working on a good Digimon team and clearing the Offline Coliseum
- Getting all titles, accessories, and avatars from the Online Coliseum
- Finishing all available Main and Side Quests to advance your Hacker Rank
- Clearing the Abyss Server
- Sampling all Coffee Flavors
