Atomfall — Platinum Guide

0%0/55
Required for Platinum → counts toward the bar
conseilHelpful but not mandatory → doesn't count
55 trophies in total (base game 37 + Wicked Isle 9 + The Red Strain 9). Both expansions are separate purchases, required for the Platinum
Tip
All 5 base-game regions are open from the very start, in any order: no linear progression or chapter locks
Tip
No trophy is tied to difficulty: pick Easy combat settings freely if needed, it blocks nothing
Tip
6 mutually exclusive endings in the base game (only one per save), 3 more in Wicked Isle, 2 more in The Red Strain: see the dedicated tabs
Tip
One well-placed backup save is enough to get EVERY base-game ending without restarting the whole playthrough
Tip
POINT OF NO RETURN (base game): once you enter the Oberon site without a backup save, whichever ending you commit to becomes the only one possible for that save
Point of no return
POINT OF NO RETURN (Wicked Isle): right after unlocking "Exhumation", make a separate save before using the Abbot's Head Reliquary, that's where Talking down the Angel / Joining the Angel branch apart
Point of no return
POINT OF NO RETURN (The Red Strain): once Permission Level Four is reached and Oberon is unlocked, save before loading the fifth brain at the Command Centre, that choice permanently locks out the other ending
Point of no return
2 playthroughs are enough overall: one full exploration run with multiple saves for every ending plus all collectibles, and a second, fast run dedicated to Quick Exit (under 5 hours)
Tip
Collectible progress (notes, audio logs, comics...) does not carry over to a new game: keep your exploration save as your main save until the very end
