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.

• Break up the fight between Arlen and Rayen and then ignore Arlen instead of punching him.
  
• Choose to save Rayen's leg.
  
• Get the laser crystal for Virgil (this is a scavenge item and obtained doing the Doctor Approved achievement).
  
• Find the cigar (this is a scavenge item and obtained doing the Stogie for Fogey achievement)
  
• Throw Cox in the brig instead of throwing him out of the airlock.
