THE PORTOPIA SERIAL MURDER CASE: Walkthrough & Achievement Guide

Here is a walkthrough with all achievements guide for the new game SQUARE ENIX AI Tech Preview: THE PORTOPIA SERIAL MURDER CASE.

Note: this walkthrough is incomplete and will updated in near future!


Regarding Treshold 8800.00

With the current build (as of 04/23/2023) there’s a common bug in which none of your commands is accepted by the game and Yasu (your pardner) dismissed you.

User “Sanugia” found a quickfix about this issue.

Quote: I found the solution for this. Go to the “LocalLow” folder and search for the game’s name. Within the folder of the game’s name is a file called “userConfig”. There the NLU_Threshold was set to 88 for me. I set it to 0,88, and now it is back to 88 in the game itself.

It’s on:

HOWEVER this issue also corrupts some saves, not being possible to advance. To be safe, you must play Portopia in one sitting.

(that’s why this guide might take awhile)



If you didn’t read the previous section, MAKE SURE TO CHECK YOUR THRESHOLD!

As soon as the game starts, use the PAUSE buttom (if your keyboard is different press Fn + Pause). Take a deep breath and get ready to type.

Achievement: Good Cop, Bad Cop
Achievement: Case Closed


I wrote the guide as I was playing so some parts might be rough than others.

Also, I couldn’t unlock some achievements on the first playtrhough.

I’ll play more times just so I can figure the other achievements + optimize the run.

I think whenever you find victims two and three, when Yasu asks “let’s close the case”, you have to arrest one of the other suspects to unlock them. Might need some testing, but you’re welcome to try and tell me the outcomes!

Thank you so much for reading.
