Overview
A short guide on how to get the Unique Soul Achievement. (NOTE: This does NOT apply to the new route for the Executive Edition.)
Unlocking the Achievement
First, let make this clear: this should be the LAST achievement you aim for. The game is super hard so you should play it a few times to get a good idea of the game’s layout and how to avoid damage/deal with enemies before you start. It’s best if you beat the game and get the other achievements you want, then do a power run to get Unique Soul on its own.
The most important thing you need to know about this achievement is that you have to complete the WHOLE game in order to unlock it. You cannot die until you reach the autosave area, and you cannot leave early. The achievement will only unlock if you’ve played the whole thing without using a photocopier once (save for the very first time you use it automatically at the beginning with Hugo) by the time you have Rei take over as CEO/save Domori.
The game gives you one autosave point where you can die without losing your progress/having to start all over again: when the witch takes over the canteen after Hugo’s party. This is a good moment to pause the game if you need to. Be sure to stock up on food and drink whenever you can, as that will literally be a lifesaver.
Afterword
