Digimon Story: Cyber Sleuth Walkthrough

You play a young hacker in near-future Tokyo who, after an accident in the digital network EDEN, can travel between the real world and cyberspace — and takes on cases as a Cyber Sleuth. The story runs across roughly 20 chapters ("Cases"), around 40–50 hours. Here's how to keep your team strong and where to find the full step-by-step.

How to not get stuck

Scan everything. Fighting a Digimon raises its scan %; hit 100%+ to convert it and add it to your farm. More scans = more of your roster.
Mind your Memory. Your party is limited by Memory, not slots — a few strong high-cost Digimon or many cheap ones. Balance it for each fight.
Use the type triangle. Vaccine beats Virus, Virus beats Data, Data beats Vaccine — plus elemental weaknesses. Bring the right attackers to each boss.
De-digivolve to power up. Sending a Digimon back down and re-raising it boosts its ABI, unlocking stronger Megas — see the Digivolution Guide.

Should I play Cyber Sleuth or Hacker's Memory first?+
