Quarantine 37 is a supplement for Stargrave, in which the players lead their team of Free Traders into an abandoned space station, looking for lost technology as well as potentially unique research and experiments. Unfortunately, a few of those “experiments” have escaped and still roam the tight, dark confines of the station. Along with a host of new scenarios, this book also contains new technology, soldiers, aliens, and ship options for the players to upgrade their forces.
