Sacramento… We Have a Problem!
Most cowpokes with a lick of sense know the recent alliance between Gomorra's resident crackpot scientists, the Collegium, and Dr. Darious Hellstromme spells trouble. And these two groups might just whip out a thesaurus for even more chaotic misadventure!
In this 64-page adventure, the posse finds themselves thrown into a breakneck chase through the Great Maze to recover Fineas Von Landingham's airship and a top-secret Collegium project to boot! Are these events related? It wouldn't be much of a conspiracy if they weren't!
As if this weren't bad enough, the heroes might be forced to enter the slimy world of territorial politics! That ought to send a shiver down even a Harrowed's rotten spine!
Like Ghost Busters—a great way to lead into this adventure, by the way!—Rain o' Terror gives your posse the chance to influence the course of events in the Maze and Weird West in a major way. If they play their cards right, they may even carve their names on the list of Deadlands' greatest heroes!
