Soul Hackers 2 Quests Guide: A list of all requests and how to complete them

by Adam Vitale on 26 August, 2022

Soul Hackers 2 has a series of sidequests just like most RPGs, but they are overall pretty simple and straightforward. For the most part, you'll pick up these quests from a list at Club Cretaceous in Karakucho, which you'll be introduced to within the game's opening hour. Outside of the requests given here, there are just a handful of quests that are found elsewhere, like in the game's dungeon areas.

As you progress through Soul Hackers 2, the game will explicitly tell you when new quests are available at Club Cretaceous, so you do not need to check back blindly. Also, oftentimes certain quests will require earlier quests to have been done first, so it's best to simply knock quests out as soon as possible.

It's worth mentioning that there are three quests that we believe are missable if you do not complete them before a certain cutoff point in the game. These three quests are the ones given by Flamma, and the cutoff point for these quests is after defeating the boss at the West Shipping District:

Does Aion Dream of Electric Sheep?
Story of Your Love
Hopes, Dreams, and Aion

We'll place another warning later in the guide about this cutoff point, to make sure it's clear when these quests should be done by.

Without further ado, find RPG Site's Soul Hackers 2 Quest Guide below. Let us know in the comments if you see any omissions or mistakes!

Madam Ginko, the host at Club Cretaceous, facilitates quests for the local populace.
