The Expanse: A Telltale Series: 100% Achievement Guide

This guide is a full achievement guide for The Expanse: A Telltale Series, with all 35 achievements.

Introduction

Welcome to my The Expanse: A Telltale Series achievement guide! Unlike most Telltale games, there are achievements based on collectables as well as decisions. Some collectables you get or decisions you make will directly impact what achievements you can get right until the end of the game. Naturally, this guide will include spoilers, so if you don't want spoilers you might want to complete the main story first. However, if you already have completed it or don't care about spoilers and want to do all of these in a single playthrough, I've added the important actions and decisions you need to do in each episode so you're aware of what you need to do from the get-go.

Episode 1

• Find the cigar (this is a scavenge item and obtained doing the Stogie for Fogey achievement)

@john doe Ah, sorry to hear :( Each section for the episodes has the important actions/choices at the beginning so you know what you need to do, which should help avoid these types of missable bits. Some of the achievements do depend on collectables which are easily missed.

[john doe]

i did break up the fight and also saved his leg in episode 1 but i never found the medicine in episode 2 ugh so stupid so maya died just because i could not find the medicine how lame.

[Moon]

@john doe Sounds like you don't have a high enough relationship with Rayen. From what I understand, you need to do all three of the following: break up the fight with his brother and saved his leg in episode 1 and help him find medicine for his brother in episode 2.

[john doe]

i choose to trust rayan in episode 3 and maya still died i dont understand?
