What it is about
Derelict Ship Dungeon Generator is a system-neutral toolkit for mapping and running derelict starship crawls using nothing but graph paper, a pencil, and D100 rolls. Build tense, forward-moving “ship dungeons” room by room—then stock them with hazards, salvage, and strange discoveries using compact, print-friendly zone tables.
This book is designed for fast table use: every zone is a single-page reference with no table spillover and no “flip to continue” flow. It’s equally useful for solo play, GM prep, or improvising a derelict during play.
What’s inside
Core Mapping Page: a complete D100 engine for
Room footprint
Exits / connections
Connection form (corridors, junctions, nodes)
Room state (dark, damaged, venting, contaminated, etc.)
Barriers & vertical movement (ladders, lifts, crawl ducts, collapses)
8 Zone Pages (each on one page) with D100 tables for:
Area • Feature • Peril • Opportunity
Zones included: Access, Engineering, Operations, Cargo, Living, Medical, Research, Special/Core
Quick Reference Page: mapping sequence + symbol key for graph paper
Mission Hooks: D100 objectives + D100 complications to give every crawl a purpose
Worked Example: a short 6–8 room crawl with a map sketch and roll results
How it works (at the table)
Roll a room footprint and draw it on graph paper
Roll exits and connections, then extend forward
Roll the room’s state and barriers to create tactical choices
Use the current zone page to add a Feature, Peril, or Opportunity
Keep pushing deeper until you find the objective—or the ship finds you
Perfect for
Solo exploration and journaling play
One-shot derelict missions
Drop-in locations for any sci-fi campaign
Procedural map generation when you don’t want to prep a full deckplan
Format
PDF (print-friendly reference)
System-neutral. Use with Traveller-style sci-fi, OSR space crawls, narrative sci-fi, or your own ruleset.
