Agatha Christie - Hercule Poirot: The First Cases Achievement Guide

Guide for all achievements

Introduction

This is a walkthrough including all achievements. I was logging my actions as I was playing and unlocked all achievements in one playthrough. Some actions might seem confused or out of order, but I didn’t experience any technical difficulties reported by some players so it might be a good idea to follow them.

Inspecting all objects was always my first step in every location, usually in clockwise way.

Some achievements which require inspecting multiple objects are my rough guesses since there’s no tracking in the game and I’m unable to tell the exact requirements. However since I was able to unlock all achievements the walkthrough covers them anyway.

Objects to inspect are numbered.

Deductions in mind maps are shown in frames.

Choices don’t matter until the last chapter where you can fail the conversation and miss one achievement. In chapters 1-8 the the game will keep rolling back the dialogues until you get them right, in chapter 9 the game will progress and you will get a different ending.

Chapter 9 – The Denouement

This chapter is one long dialogue scene in which you can actually fail the dialogues depending on your choices. You will be talking to four characters and your approach will determine the ending. Only one ending grants all the achievements. If you pick a wrong option and don’t have a backup save you’ll have to play the whole game from the beginning since there’s no chapter select.

Best ending:

  • Jackie: Accusing, Forceful, Disgust
  • Hugo: Direct, Sarcastic, Sympathetic
  • Ernesto: Direct, Straightforward, Assertive
  • Cassandra: Suggestive, Antagonising, Sympathetic
