Chapter guide FAQ
How many chapters are in The Sinking City 2?
The main campaign walkthrough is organized into five chapters: A New Day, The Wake-Up Call, A Sight For Sore Eyes, Time and Tide, and Cold Comfort.
Which guide should I use for one puzzle or code?
Use the puzzle solutions and safe codes hub, or the focused link listed under your current chapter. This page deliberately does not print the answers.
Does this chapter guide reveal the ending?
No. It shows chapter names, broad locations and guide choices. The full walkthrough, boss guide and ending page are separate and labeled before deeper spoilers.
Is there a verified point of no return?
This page does not publish one because the route sources used here do not establish a verified point-of-no-return marker. Follow the chapter-order collectible checklists as you enter each region.
Scope and sources
Chapter names, broad objectives and region labels are condensed from our dated full walkthrough, which identifies the editorial walkthroughs used for route verification.
No completion-time or point-of-no-return claim is added here because neither is established by the cited route material.
