The Space: 1999 Roleplaying Game will allow you to join the crew of Moonbase Alpha! Created by Gerry and Sylvia Anderson (Thunderbirds, Joe 90, and so much more) in 1975, the British show told the story of a moonbase after a nuclear explosion throws the moon into deep space. The game is written by Andrew Peregrine (Dune) and Modiphius Entertainment, and is powered by Modiphius' 2d20 system.
