Want to master all of the side quests? Check out our Digimon Story: Cyber Sleuth – Hackers Memory Case Guide for a step by step guide on unlocking and completing all of the cases we’ve discovered and finished on the BBS board.
Cases are special side quests in Digimon Story: Cyber Sleuth – Hackers Memory. There are three distinct types. Important Cases that are required to progress through the story, standard Cases that are just for the rewards and story, and DigiFarm Cases that are missions related to your DigiFarm. You can tell which is which by the color code bar on the left of the email.
Important Cases – Red
Normal Cases- Yellow
DigiFarm Cases – Green
Below is a list of all Cases in Digimon Story: Cyber Sleuth – Hackers Memory in a Chapter by Chapter format. We focus primarily on the Normal and DigiFarm Cases as the Important ones are story-based and rarely difficult. The DigiFarm Cases are mostly repeatable, except the eliminating of hackers, so you will often find that you discover them in a different location to us, but it doesn’t really matter either way. All of the DigiFarm cases are marked with (Farm).
Some of the Cases are Domination cases where you can choose friends to bring with you. Be sure to make the right choices with our Popularity Events Guide.
This is one of the first side cases you can take on. After you complete the main mission for the Digilab women these will unlock. Take this quest and you will be warped to Kowloon level one. Talk to the woman in the park there and she will ask if you can hear the singing. Follow the path to the end of Kowloon level one and you will face a Lalamon there.

This is one of the first side cases you can take on. The Missing Girl quest will take you to Kowloon level one. Talk to the people in the Junk plaza and they will say they have never heard of Rumi. A Lunamon will appear and start talking to you. She takes you to where Remi is and you have to face off with Lunamon. I’m not sure what she did turn one but she killed my Agumon in a shot. The rest of the fight was pretty simple, just be sure to burn her down before she can murder your other Digimon. When Lunamon is defeated you will be the mission.
This Case is discovered when Investigating in the DigiFarm. This is a team battle where you have to earn points by taking over squares on the map. Some are worth five points and others are worth one. I brought Ryuji and Chitose for the battle since they had strong Digimon. Have Ryuji take the middle two squares so you have ten points in a well defended spot. From there you can use yourself and Chitose to get the five pointers on the outskirts. You need to reach 35 before the enemy or before 30 turns to win. If an enemy is on a square you want, fight them and take it for yourself.

As usual you will use your strongest member, most likely you, to hold the center points. The flanks should be gotten by your allies.

You will get this side mission at the start of Chapter 7. This is a territory battle but is different from the ones you have done before. You need to find all the hacker points and take them from the enemy and then face their leader. You can just face their leader right away but they will have an advantage and your Digimon will be paralyzed. It is worth getting all the hacking points just to do battle with the extra four trainers for that easy experience. Leave your partner to protect them once you get a Hack point and then take the rest yourself. The boss has a couple of strong Digimon so be ready for a fight.
You will get this side mission at the start of Chapter 7. When you get to the Beetle Arena you will have to get past two tree Digimon. Fight them and go past, don’t forget the chest near them. Now use the elevators to go up to the terminals in the area. There are two and you need to activate both to take down the green wall blocking the path to the Beetle Fight.

One of the first normal side missions you get in Chapter 8. This is another one where you need to find the four hack points and take them over. This one isn’t as bad because you just lose speed if you don’t do take the points. Still there are four other trainers in the area and fighting all them is worth the experience. Take all the points and face the leader to beat the mission.

You will be warped to where you need to be and there are three walls you have to beat. When you beat all the walls continue through the area until you reach the top and you will face off with Gryphonmon. I had one Digimon weak to him and he hit like a truck so the battles are getting tougher, but it isn’t that bad here.
One of the first normal side missions you get in Chapter 9. Another one of those missions where you have to hack a few switches and then face off with a trainer. There are five switches this time and you will want to hack them all because these ones confuse your Digimon. Take all the switches and then take out the leader to win the mission.
One of the first normal side missions you get in Chapter 10. Another one of those missions where you have to hack a few switches and then face off with a trainer. This time I tired to just kill the leader without hacking all the switches, big mistake. She is way stronger if you don’t hack the switches. One is easily missable right at the start, it is to the left but you need to make a bridge to get to it. The rest are easy to find so make sure you get them all before fighting the leader.
One of the first normal side missions you get in Chapter 10. First head to Kowloon level 4 and speak with the Veggiemon in the second area. He will tell you about URL they use for delivery. Go to the delivery URL but make sure you can break a firewall of level 3. This means you need four Digimon in your party of at least Champion ranking. Head to end of the area and you will face off with WereGarurumon. Return to your PC when you are done for your reward.
This is an investigation mission from the farm you get during Chapter 10. Head down to Kowloon level 4 and in the second area you will find an old man you need to battle. Beat him and return for your reward.

After some of the story bits in Chapter 11 you will get a ton of side missions and this is one of them. You need to head down to Under Kowloon level 4 and look for something making a hammering sound. In the second area of Under Kowloon level 4 there are three people you will need to talk with. After you talk to the three, talk to the first one again and she will say I hope you get cursed too. Just head a bit deeper into Under Kowloon 4 and you will find a Digimon with a huge hammer, Beat it and return to your PC for a reward.

At the end I told the Digimon it needs more then a quiz and you end up battling CatchMamemon. After you beat him down you can pick the name of the park, it’s up to you the choice doesn’t matter. After that you return to your PC and get your reward.
After some of the story bits in Chapter 11 you will get a ton of side missions and this is one of them. You are warped to their area and you need to take over their hack points.

After some of the story bits in Chapter 11 you will get a ton of side missions and this is one of them. You are warped to their area and you need to take over their hack points. There are five hack points in this one and I highly recommend you take them all. The leader only has two Digimon but they have a lot of HP and defense so it is a long drawn out fight. Focus on one and when it is a one on three you can easily win. Return to the PC for your reward.
After some of the story bits in Chapter 11 you will get a ton of side missions and this is one of them. First you are sent to the Hoska Server to look for clues. When you arrive you will have a pretty easy fight and Piximon will run away. Follow Piximon down the left side of the map and you will have a few fights until you reach the end. Beat the leader and Piximon to complete the mission. There are a couple choices at the end but none if it matters, you agree not to tell the police regardless of what you pick.
There are no side missions in Chapter 12 but once you start up Chapter 13 you will run into a few. This is the only territory battle and it isn’t a super hard one.

Beat the mission and return to your PC.

Take the first elevator down and then enter the first room for bonus chests. Leave and take the next path down and then take the elevator down to floor 666. Follow that to the security door and bring it down. It has some HP and can do a ton of damage if it reaches 100% so bring your heavy hitters. Take next elevator to b9–99-9–9. After you beat the boss there is a choice but again it doesn’t matter, Beelzemon comes to take the kill.

When you reach the end you need to go the right left side of the room for one more Hacker point. Take the teleporter near the leader and this will lead to your last Hack point and a medal.
