SIS/TR: A Rare Geometry + PDF

It is unknown how the crew of the Vespucci 7 attracted the curiosity of SIS/TR [Starborn Invasion System/Turret Regenerator], but it is actively attempting to bring order to the natural chaos human life creates.

"Brooding atmosphere, A.I. gone wrong, and a rich tapestry of gore-soaked hallways ringing out with screams of the damned await you in SIS/TR: A Rare Geometry. If you like your horror Weird, you won't be disappointed. This thing drips."  -Jarrett Crader

About the book:

Part rescue mission, part resource discovery, SIS/TR: A Rare Geometry is unlike anything your players have ever encountered.

25 rooms and thousands of ways SIS/TR can attack, infect, and hack their way through your party. SIS/TR is already a puzzle players have to solve - the ship functions as a puzzle within a puzzle as SIS/TR consumes resources, manipulates rooms, and broadcasts horror throughout the captured ship.
A clever crew can even discover SIS/TR's unique refining abilities, allowing them to craft odd items from its system.

SIS/TR: A Rare Geometry includes rules and stats for SIS/TR, SIS/TR Mothership RPG operating manual, as well as a vicious starship adventure.
