PS3
Dead Space 3 asks you to complete campaigns with different rules rather than simply raise the difficulty. Your initial run builds the main collection and organises Carver’s assignments with a partner; Classic, Pure Survival and Hardcore should be treated as separate routes. Before committing to collection, verify that you can actually start a cooperative session on your PS3: some required areas do not appear during solo play. Cooperative assignments and special-campaign rules need different preparation: effective equipment cannot replace access to Carver’s areas or completion of each required mode.
Base-game trophy roadmap; expansions with additional trophy groups are excluded from the platinum.
- Required difficulty: Dedicated clears in Classic, Pure Survival and Hardcore.
- Missable trophies: Chapter select supports cleanup; collections include cooperative areas.
- Online: A second online player is required for cooperative missions and actions. Test access before collecting.
Keep a main save for collection
Start with the normal campaign and use that save as the reference for parts, circuits, artifacts and logs. Do not mix its counters with special-mode saves: inspect the chapter summary and record the missing category. After a new item, reach the next checkpoint; quitting or dying before progress is recorded may require collecting it again.
- Check every category in the chapter summary after reaching a checkpoint.
Arrange Carver’s assignments first
Collections in chapters 4, 11 and 14 include cooperative sections. Arrange those sessions with a partner and both inspect the summary after each assignment. Combine item sharing, blueprint sharing, execution rescue and revives in the same session: these are different requirements, so merely playing together can leave them unfinished.
- Complete cooperative missions and deliberately perform the team interactions.
Respect Classic’s separate rules
The first ending unlocks the special campaigns. In Classic, plan around the weapons and resources that mode provides rather than assume your normal save’s unrestricted crafting. Use familiar encounters to decide when to stop an enemy with stasis and when to move through an area; the objective is a mode clear, not rebuilding the entire collection here.
- Finish Classic as a separate objective.
Manage crafting in Pure Survival
Dedicate a campaign to Pure Survival and frequently inspect materials, ammunition and healing rather than run out in combat. Treat the bench as preparation: before leaving a safe area, check what your current weapons consume. Keep a dependable setup for regular enemies so experimentation does not exhaust the supplies needed to continue.
- Prepare ammunition and healing at the bench before demanding sections.
Prepare before starting Hardcore
Leave Hardcore until traps, chases and flight sequences are familiar. Do not confuse being able to stop a session with protection from death: this mode imposes a much harsher progress penalty. A personal checklist of sections that killed you in earlier campaigns is more useful than a powerful weapon chosen at the last moment. Awakened is an additional group and replaces none of the base-game clears.
- Review lethal sections and confirm Hardcore completion on its own save.

Frequently asked questions
Can I collect everything solo?
No. Some collection items belong to co-op-only areas; chapter select does not remove that condition.
Does a hard campaign replace Classic and Pure Survival?
No. The list requires those specific modes, each with its own rules and clear.
Is Awakened required for platinum?
Its additional group is separate from the base platinum. Still make sure you compare items against the correct campaign collection.
