About the adventure

OPEN-WORLD SANDBOX SCI-HORROR ONE-SHOT | BEGINNERS WELCOME ========================================================= INTELLIGENCE REPORT: CLOUDBANK SYNTHETIC PRODUCTION FACILITY A.K.A. "THE DEEP" AUTHOR: CMDR. RACHEL KILROY EXECUTIVE EYES ONLY AI superintelligence known as "MONARCH" retains control of station. Attempts to re-establish control continue to fail. Expedition casualty rate remains 100%. Artifact retrieval rate 0%. Post-mortem autopsies reveal two subordinates from last expedition as infiltrator androids designed by MONARCH. Unable to determine whether subordinates were androids at time of arrival or brainscanned and replaced by MONARCH aboard station. Remain unable to distinguish infiltrator androids from humans premortem. Crew morale low. Chief medical officer indicates over a third of crew experiencing severe paranoia and have minimal combat effectiveness. Please advise. Blockade of station continues as instructed. Three "diver" teams attempting to run blockade intercepted and destroyed since last report. Principal diver Arkady still at large, believed to be coordinating aforementioned scavengers. ========================================================= ITEM: False Memory Disk CLIENT: Anonymous BOUNTY: 1,500,000cr LOCATION: The Deep (Cloudbank Synthetic Production Facility) ITEM DESCRIPTION: Circular disk protected by 3.5mm square metal case. Able to make android believe it is human. Do not insert.

And just maybe, get out alive. ☠️ Encounter a wide variety of NPCs, factions, locations, and horrors from the "Gradient Descent" module. ☠️ Rich descriptions and deeply realized characters—with unique, stylized character voices—and the vividness of the horror scaled to the comfort level of the table. ☠️ New to Mothership?

About me

Hi! I'm Jess, and I'm: ⭐ An award-winning TTRPG designer ⭐ An experienced actual play podcaster ⭐ A published sci-fi author ⭐ A GM of over 15 years ⭐ A professional educator I especially love: 🎲 Running open-world, open-ended sandbox games driven by player agency and dynamic, interconnected factions, NPC relationships, objectives to make the world feel alive. 🎲 Sci-fi systems like Mothership and Shadowrun—I even have a circuitboard tattoo on my scalp. I also run my own games, like the Starship Troopers and Helldivers-inspired 'narrative wargame' PLANET FIST! When I GM: 🎲 I'm careful to make sure every player gets their turn in the spotlight. 🎲 I always weave player-created backstories into the existing world. 🎲 As a designer of multiple GMless games, I'm skilled at bringing the best contributions out of other players at the table, enabling them to contribute and help shape the overall world. 🎲 My players praise my knack for drawing connections between characters and stories, in ways that make the world feel rich and inhabited. You can hear me GM on AP podcasts like Role Playing Public Radio, and facilitate my award-winning GMless games Going Rogue and I Have the High Ground on podcasts like A More Civilized Age, One Shot, Party of One, and more.

Character creation

Creating your character

Mothership character creation is intentionally very fast—it's intended that if a player's character dies at the table, they roll up a new one and rejoin the action. As such, and in order to create compelling narrative connections between crewmembers, we will create characters together at the table. I'll be there to guide with any rules questions, and even with new players, character creation is unlikely to take any more than 30 minutes—we'll start playing immediately after! Players roll a character using the standard instructions from the official Mothership Player Survival Guide with the following exceptions: ✅ They may assign their randomly rolled stats to attributes of their choice ✅ They may roll twice on tables and take their preferred results ✅ Players who want to include third-party Mothership content in their character at creation can message me beforehand and we can discuss if it fits!

What to expect

Preparing for the session

✅ Players will need to join either a Discord server or Discord group chat (if they would prefer not to join a new server) ✅ The game will be hosted via a Discord audio call ✅ Players will be polled on both their comfort and desire with inclusion of video—if everyone is comfortable and anyone desires it, we'll play with video on ✅ If some players are uncomfortable with video, but anyone would like me as GM to have my video on, I am also opening to being the only one on video! ✅ Google Sheets will be used for character sheets ✅ I'll show maps through Discord's chat or whiteboard features, or a simple free VTT like Owlbear Rodeo—happy to use whatever platform is easiest for a given table!

Homebrew rules

For those familiar with the Gradient Descent module, I make a small number of changes to the story of the A Pound of Flesh module for reasons of safety or making it easier to run as a one-shot: ⚠️ The "Hel" floor upon which (in the module as written) there are typically children androids being eternally tortured is instead shuttered, the floor having been lost to a fire well before Monarch's takeover. ⚠️ [SPOILERS] MONARCH itself is splintered into multiple versions, with different personalities and different domains within the station. Additionally, my Mothership one-shots use a small set of well-tested house rules, many of which come from the list of suggested potential house rules in the official Mothership Warden Operation's Manual (i.e. the GM's guide.) These include: 🎲 MODIFIED ARMOR DEGRADATION: Upon taking damage in excess of your armor’s AP, halve its AP, rounding down. At 0HP, it’s destroyed. 🎲 MODIFIED IMPENETRABLE WOUNDS: You cannot take 2 Wounds in one instance of damage; if you would do so, you remain at 1 HP.

Safety

How Jess creates a safe table

Given that Mothership is a horror game, the proper use of safety tools & safety discussions is particularly important. To that end: ✅ At the beginning of the session will have a discussion of 'how hard we want to go at' various common horror elements, and I will adjust my GMing and descriptions appropriately ✅ Topics that are triggering for any player (even those that appear in the official module) will be removed, and descriptions of elements like violence, gore, and more will always be adjusted to the comfort level of the player who is least comfortable with those depictions ✅ A Lines and Veils document will be sent out beforehand for players to add lines and veils, then reviewed at the beginning of each session ✅ Players may send X (stop), N (change direction), or Os in chat or by indicating them verbally—as I always tell my players, I used the X-card live on a stream demonstrating one of my own games, so believe me, it's totally okay to use the X-card! ✅ There is an Open Door policy, and players are welcome to leave or pause play at any time
