Dark Moon (formerly known as BSG Express), is a game of deception and betrayal at the cold edge of space. You are a crew member on a deep space mining expedition to Titan, the dark moon of Saturn. During a routine excavation, an "incident" occurs whereby some of the crew become infected with an unknown virus, and become paranoid, deceitful, and violent, trying to destroy the others. At the start of the game, players are divided into two teams: Uninfected and Infected. The Uninfected team simply needs to survive until the end of the game, while the Infected team secretly attempts to destroy them. Each player knows which team they are on, but does not know which team the other players are on! Who is your teammate and who is your enemy? Can you trust your best friend? And why doesn't anyone trust you when you tell them you're one of the good guys?! Roll dice, overcome traumatic events, throw your friends in quarantine when you don’t believe them, and (if you're Infected) betray everyone at just the right moment to secure victory! Dark Moon, in its former incarnation as BSG Express, was the most downloaded print-and-play game ever on Board Game Geek. Dark Moon has now been re-themed, re-imagined, streamlined, and professionally published in this new edition. If you like the hidden traitor mechanics of Battlestar Galactica but are not fond of the 3 plus hour game play times often associated with it, you will love the fast-paced nature of Dark Moon, which clocks in at 60-75 minutes in length!
