The main story follows a four-act structure: Boat Arkham opens with Calvin "Cal" Rafferty arriving in the flooded 1920s city, the hospital and other survival-horror regions make up the middle acts, and the late regions close the Cal Rafferty and Faye Bennett storyline. This page is the high-level walkthrough: it covers the four-act overview and resource planning for The Sinking City 2 walkthrough, with chapter-by-chapter puzzle answers cross-linked to the [Sinking City 2 demo walkthrough page](/demo-walkthrough).
