Chapters and areas
The base campaign is organized as five named chapters; this page lists their current order and a bounded ten-broadcast Mushroom Jack checklist without inventing a chapter-select or point-of-no-return system.
Verified campaign shape · five chapters
The Sinking City 2 has five base-campaign chapters: A New Day, The Wake-Up Call, A Sight For Sore Eyes, Time and Tide, and Cold Comfort.
The independent PC Gamer review describes the full campaign as five chapters, each covering a different location. GameSpew's current full walkthrough uses the same five chapter headings in order. The checklist below also gives the ten Mushroom Jack radio broadcasts named by two independent collectible references, while keeping optional cases and later DLC separate from the chapter count.
01 · Do this
Follow the route in order.
- 01
1. A New Day — the opening chapter and first route into the game's investigation and survival-horror structure.
- 02
2. The Wake-Up Call — the second named campaign chapter in the current full-release walkthrough.
- 03
3. A Sight For Sore Eyes — the third named chapter; its route includes the Akeley Hospital investigation material covered by the walkthrough.
- 04
4. Time and Tide — the fourth named chapter, including the later Fish Market route in the current walkthrough.
- 05
5. Cold Comfort — the fifth named chapter and final chapter heading in the current base-campaign walkthrough.
- 06
Mushroom Jack / radio checklist — The current collectible references list ten broadcasts for the Mycophile chain. Listen until the codex entry updates, and sweep each location before advancing: The Woman At The Door (Apartment 1/opening apartment), The Perfect Day (Church Nave loft by the Star door), The Missing Mayor (bar behind the safe room at the whale blockage), The Song of the Universe (Devil's Reef Hotel reception), The Insatiable Beast (Caduceus-Key Pharmacy off Hospital Reception), The Eyes Have It (Hospital courtyard gazebo), The Wickedness of West (Manipulations Room by the pink Prism station), The Word on the Wind (Fish Market Guard Post opened with a Leyden Jar), The Passage of Time (the wreck's safe-room route after the Broken Hold), and The Path (the late Badlands/Elder Things necropolis route).

Treat optional investigations and post-launch story DLC as side content, not additional base-campaign chapters, unless a later official release changes that structure.
02 · Confirm
What success looks like.
- The current base campaign count is five chapters.
- The chapter names are A New Day, The Wake-Up Call, A Sight For Sore Eyes, Time and Tide, and Cold Comfort.
- The bounded Mushroom Jack checklist contains ten named broadcasts; listening until each codex entry updates keeps the Mycophile sweep auditable by chapter and area.
- Optional investigations and Holloway Manor are kept separate from the five-chapter base-campaign count.
03 · Boundaries
Opening-route boundaries.
- The sources support the five-chapter count and headings; they do not establish a chapter-select menu, a universal point of no return, or a guaranteed save-slot rule.
- The chapter names are not a complete room-by-room map. Use the location-specific puzzle, safe, and weapon pages for route steps inside a chapter.
- The ten-radio list is a guide-reference checklist, not an official achievement database or a guarantee that a later patch cannot move a collectible. The sources do not establish a chapter-select recovery route after a missed broadcast.
- DLC and later post-launch chapters would need a separate current-release check rather than being silently appended to this base-campaign list.
04 · Undo
If the route stalls.
- No setting or file change is required. If an objective seems out of order, follow the active case marker and return to optional rooms after their gates open.
- Do not restart a save merely because a guide uses a different area heading; compare the chapter name and current objective first.
