Merging the power of Shy Plutonium with new starship technologies has allowed the U.E.S. Science Corps to reach the distant stars of Alpha Centauri, and discover the planet Terra Proxima. Strange ruins and vast fields of fungi cover much of the planet. Eager for knowledge, the U.E.S. authorizes colonization! Welcome to the second installment of Space Base Saga Expansions. This is a collection of games with a linked story that introduce new content to Space Base via a narrative structure. Not only are new ships added, but new scenarios are included as well. Once the story is completed, it may be replayed or the contents may be added to the core set.
