Planet Exploration Generator - A Sci-Fi Horror RPG Toolkit - 20 Biomes

Planet Exploration Generator — A Sci-Fi Horror RPG Toolkit — 20 Biomes Your planet has stats. Now what? You've got the atmosphere composition, the gravity rating, the temperature range. Your crew breaks orbit, the lander touches down, the ramp drops — and a player asks: "What do we see?" That's where most tools stop. This is where this book starts. What This Book Does The Planet Exploration Generator picks up where planet creation tools leave off. It gives you rollable tables organized by biome that turn any planet into a playable ground-level session — in about five minutes, without prep. Roll a biome. Roll a first impression. Roll a point of interest. You now have an opening scene. The rest emerges from player decisions and the tables you have open in front of you. Built primarily for Alien RPG and Mothership, but system-agnostic by design. No stat blocks, no mechanical dependencies. Just evocative, specific, gameable content that works with any sci-fi horror campaign. What You Get 20 biomes, each with 5 dedicated tables across 6 pages — from Frozen Wastes and Fungal Sprawl to Dead Cities, Living Terrain, and The Anomaly Universal tables that work with any biome: mission objectives, orbital scan results, equipment failures, NPC survivors, base camp incidents, site complications, and extraction problems The Escalation Track — a simple three-level tension mechanic that turns flat random tables into a narrative arc with a beginning, a middle, and a point of no return Over 100 pages of content, almost entirely rollable tables The 20 Biomes Frozen Wastes · Scorched Barrens · Dense Jungle · Swamplands · Volcanic Hellscape · Subterranean Networks · Dead Cities · Fungal Sprawl · Abyssal Depths · The Anomaly · Irradiated Wasteland · Ash Plains · Crystal Labyrinth · Petrified Forest · Derelict Megastructure · Dust Seas · Living Terrain · Bone Fields · Corrosive Shores · Storm Highlands Each biome chapter opens with a brief GM-facing overview explaining what makes this environment dangerous and how to set the tone. Then five tables follow in sequence: First Impressions & Sensory — what hits the crew when the ramp drops Points of Interest — where to go and what you notice on approach Life Forms & Threats — creatures, organisms, and what they do Exploration Events — escalating encounters from atmosphere to danger Salvage & Discoveries — what the crew finds, takes, and regrets taking How the Escalation Track Works Each biome's Exploration Events table is a single d20 table organized by intensity: entries 1–7 are atmospheric, 8–14 build tension, 15–20 are immediate danger. The Escalation Track tells you which band to roll in. Level 1: Roll d6 — the planet is strange but quiet. Level 2: Roll d8+6 — something has shifted, stakes are real. Level 3: Roll d6+14 — the planet stops hinting. After each event, advance one level. The track only moves forward. Sessions that started with a beautiful landscape end with someone missing and the extraction window closing. The Universal Tables These apply to every biome and cover the full arc of a planetary expedition: Mission Primary Objectives — why the crew landed, and why it's already complicated Orbital & Preliminary Scan Results — what sensors say before boots hit ground Equipment & Comm Malfunctions — gear breaks, comms go wrong Signs of Previous Expeditions — traces of whoever was here before NPC / Survivor Generator — who you find and what they're hiding Base Camp & Night Cycle Incidents — when the crew tries to sleep Complications Inside the Site — things go wrong inside structures Extraction Complications — leaving is never clean Who This Is For GMs who run sci-fi horror and need ground-level content fast. If you've ever frozen when the crew said "we start exploring", this book was written for that exact moment. Crack it open mid-session, roll, read, run. Product Details: 100+ page PDF.
