Small guide to try to help you get all the achievements in this game. They are all really easy to obtain. some of the achievements may contain spoilers.
Last Update: 30/04/2022



Hey, I have prepared this little guide to help you (in case you need it) to get all the achievements of the game. They are all very easy to obtain and I have tried not to spoil too many. I have divided the guide into:
– Story Related: are achievements related to the story and that cannot be missed. At the end of the game you will surely have unlocked these achievements. In case this is not the case, I’m sorry but it means that something went wrong. In this guide, the achievable achievements are put in order.
remember: always read all the letters.
– Non-Story Related: the ones that you won’t get during the story and that you may miss even after finishing the game.

My advice is to finish the game completely first, and then to dwell on all the other achievements.
