Evidence Checklist Tool
Use the mermaidmask.wiki Evidence Checklist to track all ~50 clues in The Mermaid Mask across Stonetop Inn, town square, and Mortuga Submarine.
The mermaidmask.wiki Evidence Checklist is a companion web tool mirroring in-game notebook progress—helping completionists track roughly fifty inspectable clues distributed across Stonetop Inn, town square, and Mortuga Submarine rooms. Unlike in-game UI, the wiki checklist supports printable layouts, co-op note sharing, and spoiler-filtered views hiding late-game locations until you mark prologue complete. It does not sync automatically with Steam cloud saves; manual checkbox updates keep session parity.
How to Use the Tool
Navigate to the Evidence Checklist interactive page from the site Tools menu (linked in site navigation when deployed). Clues group by map zone and room with columns for 2D examined, 3D rotated, and interview presented states. Toggle filters for optional versus mandatory collectibles targeting Master Archivist achievement. Cross-links jump to relevant walkthrough and puzzle pages for unresolved entries.
Why Use External Checklist
In-game notebook lacks export and aggregate completion percentage until late Act Three. Wiki checklist helps multi-platform players—Switch handheld sessions plus PC weekend continuations—avoid duplicate searches. Pairs with 3D inspect guide column reminding rotatable evidence. No account required; progress stores in browser localStorage with optional JSON export backup.
Open the tool: visit /tools/evidence-checklist/ on mermaidmask.wiki after site deployment for interactive checkboxes. This article page documents methodology; the tool interface provides live tracking.
