PS5
The Mound: Omen of Cthulhu supports solo expeditions, but its PS5 list explicitly includes actions involving other players. Plan platinum as a cooperative progression rather than describing it as entirely solo. Prioritise successful extraction, developing the galleon’s services and preparing equipment for harder contracts. This roadmap uses the actual twenty-six-trophy list; alternative lists describing unrelated bosses or locations are not a reliable completion reference.
Base-game platinum roadmap covering priority objectives, cleanup and verified requirements.
- Difficulty: The list includes a legendary mission and progression to rank thirty.
- Missable trophies: Expeditions can fail; confirm recovered items and progress after returning.
- Online: Reviving other players and interrupting an attack on an ally are required.
Learn a reliable extraction loop
Before pursuing the largest reward, learn to return with the Captain’s requested treasure. Prepare equipment and route aboard the galleon, then inspect the commission objective before landing. A Little Extra and Greed Rewarded compare recovered treasure with the expedition’s demand: discovering riches without bringing them back is insufficient. Avoid risking the entire extraction for a small additional margin until you have established a route you understand.
- Compare the Captain’s demand with treasure actually brought back.
Organise objectives with other players
Too Stubborn to Die requires fifty revives of another player, with intermediate thresholds at ten and thirty. Your own survival is a different counter. Agree on roles and safe recovery opportunities with the group instead of losing an expedition to force a revive during an uncontrolled threat. Just in Time also requires interrupting a Y’m-bhi about to grab an ally, so prepare a position from which you can observe the action and intervene at the right moment.
- Track your own revives and prepare the interruption protecting an ally.
Develop the galleon with confirmed recoveries
Logbooks, occult tools, songs and sacred figures have separate requirements. The Full Account needs thirteen recovered logbooks, whereas Nine Guardians checks nine figures crafted by the Woodworker. Do not count an object merely spotted in the jungle or materials gathered but never used. On returning, inspect galleon services and record what actually changed. Before a lengthy cooperative session, also check how your progression is recorded when joining another player’s game.
- Confirm recovered logbooks, crafted figures and unlocked services after returning.
Progress through contracts and ranks
Mid-level, advanced and legendary missions have separate trophies. Use manageable commissions to strengthen equipment and communication before accepting the required legendary one. Rank thirty is a cumulative objective and does not replace success in the correct contract. Check the seven playable characters too, because unlocking them differs from increasing rank. A table of rank, mission type and available characters prevents repeating activities that do not advance the remaining requirement.
- Confirm a successful legendary mission, rank thirty and seven unlocked characters.
Finish Codex and special attacks
Aim True counts fifty Y’m-bhi headshots, while One Clean Throw needs a spear-headshot kill on one. Long Shot instead requires an airborne Bandurria at a distance of at least fifty metres. Prepare suitable equipment for each challenge and keep the thirteen Codex pages on a separate checklist. Confirm unlocks individually; this roadmap does not promise fixed coordinates for every spawn or automatic shared progression for every participant.
- Check target, weapon and distance before attempting special attacks.

Frequently asked questions
Does solo mode make platinum entirely offline?
No. The list requires reviving other players and a challenge involving an ally. Solo-mode availability does not remove those conditions.
Is gathering materials enough for Nine Guardians?
No. The Woodworker must craft nine figures. Check actual crafting aboard the galleon after expeditions.
Does this guide guarantee identical guest and host progression?
No. Check unlocks on your own profile and available services after an initial session before investing many expeditions in somebody else’s progression.
