Starfinder Adventure Path: The Penumbra Protocol (Signal of Screams 2 of 3)

While relaxing on a posh asteroid resort, the heroes are beset by a plague of madness and horrible transformations and, after dealing with its unfortunate victims, learn these tragedies are part of plot engineered by an insane scientist trapped on the Shadow Plane. Using the funding of an amoral corporation, the scientist has crafted a mysterious signal that will spread pain from world to world. As this corruption begins to infect the heroes, they must stop the transmission at its source to save themselves-and the rest of the galaxy! A Killer App! Infected with a sickness that threatens to turn them into twisted sadists, the heroes travel to the city of Cuvacara on the planet Verces to find the possible origin of their affliction!
