Gradient Descent is a sci-fi horror megadungeon set in an abandoned android factory controlled by a powerful rogue AI known as "MONARCH." Built from the ground up for the Mothership® sci-fi horror roleplaying game.

Written by Luke Gearing (Fever Swamp, Acid Death Fantasy) and illustrated by RPG newcomer, Nick Tofani, it includes:

The CLOUDBANK Synthetics Production Facility, AKA "The Deep," a 12 level, 200+ room megadungeon. Clean layout with an eye towards usability at the table, the Deep is one of the easiest to reference and run megadungeons on the market.

The Bell, a small scavenged camp orbitting the Deep, where your players can rest and recuperate from adventuring. Contains a small crew of NPCs with their own unique rumors and agendas. 

A d100 table of powerful Artifacts created by Monarch, each with their own unique effects and potential hazards.

Campaign ready! A section on Fallout gives guidance on the potential short and long term consequences your players may face as a result of their actions in The Deep.

One shot accessible: Quick tips and tables make it easy to run a 1-3 hour "dive" into The Deep for a single night's play.

Supports different playstyles: Everything in the Deep wants something and can be reckoned or bartered or negotiated with. Great for Faction play, social roleplayers, or players who just want a difficult series of combat encounters.

A unique new condition called "The Bends" that will have your players questioning whether they are human.
