From publisher blurb: The chance find of a robot probe from an primitive extrastellar civilization promises more than just the opportunity to make a new find and the PCs a few quick credits; it also unwittingly serves as a cry for help from an entire planet. The heroes, arriving at the previously-uncontacted world, find it in danger. Will they act to save it, or bear silent witness to its destruction? The Bottle is a short adventure for 2D6 science fiction RPGs such as Cepheus Engine and the Original Science Fiction Roleplaying Game (OSFRPG.)
