PS4
Alien: Isolation rewards route knowledge and disciplined saving rather than constant combat. Separate the Hard campaign from a no-death attempt when Sevastopol is unfamiliar; learn passages and tools without putting every mistake against One Shot. Also track human casualties, android kills and collectibles separately. Some objectives demand opposing behaviour, so deliberately accumulating deaths or human kills belongs in cleanup outside the clean campaign. Mission selection helps local cleanup, but it is not a universal eraser for deaths or human casualties already recorded within the campaign you are using.
Base-game trophy roadmap; expansions with additional trophy groups are excluded from the platinum.
- Required difficulty: Hard satisfies Survivor; subsequently added Nightmare is not required.
- Missable trophies: A recorded death compromises One Shot; human kills compromise Mercy or Prudence in the relevant campaign.
- Online: Single-player campaign trophies; no multiplayer required.
Learn Sevastopol on Hard without human casualties
Hard is sufficient for Survivor; choosing Nightmare adds difficulty without another platinum condition. Avoid lethal weapons against humans during a Mercy or Prudence campaign. Androids are a different category. Assess an occupied room before crossing it; a quiet detour can resolve the objective without consuming healing or provoking a chase.
- Finish Hard while separately tracking human casualties.
Use noise and crafting to create space
Running attracts attention; identify the exit route first and choose when to move quietly. Do not treat the flamethrower as a permanent solution to every alien encounter; reserve resources for reaching your objective or save point. When component inventory fills, committing parts to available blueprints frees space rather than leaving everything in containers.
- Check your escape route and materials before entering a new area.
Protect a clean save for One Shot
Attempt the no-death run on an easier setting if you want to focus on the route alone. Distinguish an avoidable danger from an already recorded death; reloading a contaminated file does not automatically erase the event. A saved death requires an earlier clean point. Do not base the whole campaign on the assumption that you can always reload after the death screen.
- Maintain an earlier save unaffected by deaths.
Separate ID tags, archives and Nostromo logs
The Taken requires every ID tag, while Voices of Sevastopol uses a hundred-archive-log threshold; do not turn that into a requirement for every existing record. The ten Nostromo logs form another collection. Later tools open earlier routes; use summaries and mission selection to recover items, recording the required access tool instead of repeatedly trying a still-locked door.
- Compare three separate checklists and return with the required tools.
Leave deaths and kills for separate cleanup
The hundred-alien-deaths trophy conflicts with the purpose of a One Shot campaign. Accumulate human kills outside the no-kill route too. Afterwards, replay mission 5 without being killed by the alien and finish other local challenges if needed. For My Turn Now, attack an android using only the maintenance jack; weakening it with another weapon first is a different condition.
- Finish One Shot before deliberately accumulating deaths.
Trophies to watch
Survivor
Complete the game on the hardest difficulty setting
Finish Hard; selecting Nightmare is unnecessary for this condition.
One Shot
Complete the game without dying
Use a clean save and do not rely on reloading an already recorded death.
Mercy or Prudence?
Complete the game without killing any humans
Avoid human casualties; androids are not humans for this requirement.
The Taken
Collect all ID tags
Track every ID tag separately from other records.
Voices of Sevastopol
Collect 100 archive logs
Reach one hundred archive logs; Nostromo logs are a separate category.
Frequently asked questions
Does Survivor actually require Nightmare?
No. Despite the historical description saying the hardest setting, Hard satisfies the trophy; Nightmare was added later.
Do android kills invalidate Mercy or Prudence?
The condition concerns humans. Reserve objectives requiring human casualties for separate cleanup.
Can I reload any save after a death for One Shot?
No. If it already contains the death, the problem remains. You need an earlier clean point; manage saves before risky sections.
