Written by Luke Gearing (Fever Swamp, Acid Death Fantasy) and illustrated by RPG newcomer, Nick Tofani, Gradient Descent (A Mothership Module) includes:

• The CLOUDBANK Synthetics Production Facility: AKA "The Deep," a 12 level, 200+ room megadungeon. This megadungeon has a 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 orbiting 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 its own unique effects and potential hazards.
• A section on Fallout which gives guidance on the potential short- and long-term consequences your players may face as a result of their actions in The Deep.
• Quick tips and tables making it easy to run a 1-3 hour "dive" into The Deep for a single night's play.
• Supports for different play styles: Threaten, barter or negotiate for anything.
• Faction play, social roleplay, and a difficult series of combat encounters.
• A unique new condition called "The Bends" which will have your players questioning whether they are human.

This adventure is suitable for characters of any level in a survival horror setting and is sure to pose a challenge to even the most battle-hardened party.

This is not a standalone module. A copy of Mothership: A Player's Survival Guide is required to play.
