The Expanse: A Telltale Series
Achievement guide · roadmap · tracker
A Telltale choice-and-collectibles series - five episodes plus the Archangel prequel (Madame Undersecretary). 100% is one careful playthrough: none of the choices are mutually exclusive, so a single run that keeps the crew alive (
No Belter Left Behind) and grabs every collectible nets the lot.
The thing to know up front: there is no mid-episode rewind or collectibles mode. Miss a Data Log or a Scavenge Item and you replay the whole episode - completed episodes are replayable from the menu, so nothing is lost for good, it's just a full re-run. Play with a collectible video open. Tally: 21 Data Logs (6/5/4/4/2 across Ep1-5) and 24 Scavenge Items (8 each in Ep1-3 only; Ep4-5 have none).
The crew-survival cheevos are an interdependent chain across all five episodes - one missed early step (the Ep1 laser crystal, the brig choice) silently locks a later payoff - so follow a survival checklist. Most of the gift/interaction cheevos live in Episode 2, so take that one slow.
