From the rear cover:
Into the Unknown casts the players as Exploratory Scouts on board the IISS Spartan Wainwright, a Donosev-class Survey Scout. Their mission is to conduct a Class IVb survey of system N-83-Aleph and confirm an overview of the system obtained from pre-jump assessment phases conducted earlier and survey in detail and potentially inhabitable planets.
While there, they will uncover the descendants of a long-lost crew, survive the flora and fauna of a new world, and contend with a system-wide tragedy...
Adventure 4: Into the Unknown is a complete self-contained adventure that can be expanded into a complete mini-campaign that will challenge players to explore and solve problems with more than just a laser.
