From publisher blurb: A mystery scenario for the HOSTILE RPG (and Cepheus Engine). The PCs are on a routine supply run to an outlying research base on the edge of known space. When they reach their destination – something has happened to the scientists. Many base personnel have jellyfish-like creatures covering their faces and are comatose. Others are dead, but have no alien thing on their face. What's going on? What will happen next? Should the players not solve the mystery - will the same fate befall them? Welcome to LX410 - an unknown world with an unknown threat.
