What you get in your GM booklet
From your brief, AdventureEngine assembles a print-ready A4 booklet — not a generic story dump. Each section maps to something you would actually use at the table: who knows what, where to send players next, and what happens beat by beat until the truth comes out.
- Case overview
- Opening summary, event timeline, and the hidden truth — GM eyes only
- Run guide
- How to use the booklet at your table, as a one-shot or inside a campaign
- NPC & location cards
- Suspects and witnesses with motives, secrets, and what they know — plus places to search
- Phased story beats
- Playable scenes in order, each with discoveries and clues that point to the next beat
- Epilogue
- How to land the finale and wrap the session
