PS4 / PS5
Fallout 4 platinum planning happens before factions become enemies. One character can support several routes, but separate saves are needed before permanent hostilities. Combine that structure with settlement activities and character counters: completing those after an irreversible decision does not restore lost quests. Preserve a shared starting point, then complete and verify each branch without deleting the save needed for the next one.
PS4/PS5 base platinum roadmap with faction branching saves; DLC excluded.
- Required difficulty: No mandatory difficulty trophy.
- Missable trophies: Faction questlines can exclude one another.
- Online: No multiplayer required.
Join factions before choosing hostilities
Meet the Minutemen, Railroad, Brotherhood and Institute before rushing towards an ending. Initial membership is not the same as a final declaration of war. Keep a record of each faction’s main quests so you can distinguish progress towards a trophy from repeatable assignments that do not resolve its storyline.
- Record faction quests before the first hostility warnings.
Protect the Mass Fusion threshold
Retain a save before choices that make factions hostile, particularly before committing to Mass Fusion. Add another copy before later breaks without overwriting the shared base. Whenever the game warns of permanent consequences, stop and check which trophies associated with that faction have already been earned.
- Save before committing to a mission that declares hostility.
Complete one branch, then return to the shared save
After completing a route, check its trophies and reload the appropriate save for the alternative faction. Do not expect side assignments to repair a permanently hostile relationship; the issue is a narrative decision. Keep a small record of save name, accessible faction and next quest to avoid resuming from the wrong branch.
- Record which save belongs to each alternative route.
Isolate the happiness project
For Benevolent Leader, use a manageable settlement rather than changing several villages simultaneously. Check needs, assignments and defences, then observe happiness without constantly moving residents. If it falls, there will be fewer factors to inspect. Adding residents and new problems while pursuing the maximum makes the cause of stalled progress harder to identify.
- Check needs and assignments within the same settlement.
Preserve progress from cumulative activities
Lockpicking, hacking, weapon modification and exploration fit naturally into the journey. Save after a productive session because lost progress after death can also mean repeating completed activities. For magazines and bobbleheads, keep an item-level checklist: the total shows how much remains, but not where to return when one object is missing.
- Track collections by item and save after cumulative activities.

Frequently asked questions
Must I restart for every faction?
Not necessarily. Saves made before faction breaks let you resume alternative branches without repeating the whole story.
Can I recover faction trophies after the ending?
Only if the questline remains accessible or you retained an earlier save. Free exploration does not undo decisions that removed a faction.
Are expansion trophies mandatory?
No. Automatron, Far Harbor, Nuka-World and other additional groups are separate from the base-game platinum.
