PS5
Harold Halibut rewards living aboard the ship rather than merely rushing main errands. Optional encounters and activities contribute to the notebook, so chapter completion does not prove every drawing is present. Visit residents before day-ending actions and inspect pages periodically. Slow Bro adds an actual playtime requirement, not a demand to finish quickly.
Base-game roadmap for PS5. Console trophy stacks remain separate; additional groups do not replace platinum requirements.
- Required difficulty: There are no combat-difficulty challenges.
- Missable trophies: Conversations and notebook drawings may depend on the day and progression.
- Online: The platinum route can be completed offline in single player.
Explore before ending the day
Handle available Agora, laboratory and district detours before the main objective. Dialogue changes by day, and residents may later move elsewhere. After new assignments, check for side requests before resting or departing. Record chapter and subsection for cleanup rather than only a character name.
- Check available residents before advancing the day.
Compare notebook pages
Inspect the notebook and confirm which encounters actually added drawings. Speaking once does not necessarily complete a resident’s story: follow the brothers, Energy District requests and encounters opened by main events. Track pages by story section instead of relying on a general memory of visiting every corridor.
- Mark a page only once it appears in the notebook.
Follow letters and Mareaux updates
Read Buddy’s letters before delivering them and complete the whole chain. During the Blue Rock search, report each relevant step to Mareaux. Skipping reports because you know the next destination can leave Managing Upwards unfinished. Track deliveries and responses, distinguishing read letters from merely collected letters.
- Read before delivery and report every Blue Rock development.
Finish residents’ activities and conversations
Graffiti cleaning, Bierzone gossip, Onat’s performance and supporting Zoya are different tasks. Visit residents when movement is open and follow requests requiring another visit. Actually watch television and play the arcade activity for their required times; standing nearby is not equivalent. Keep these counters separate from total campaign time.
- Complete activities rather than merely entering their locations.
Protect playtime and the final audit
Slow Bro requires more than fifteen hours of play; check time before finishing. Loading an earlier section can restore its earlier state, so do not automatically combine hours across branches. Before the epilogue compare notebook, letters, exchange conversations and completed requests, preserving the main file for remaining objectives.
- Check playtime and notebook before the epilogue.
