This is a monster of a game and more for the hardcore boardgamer only. It's a fairly complex game to wrap your head around, but can be incredibly satisfying once you learn the rules.
For those unfamiliar with the Battlestar Galactica series, the story (and the game) revolves around a universe where humanity is nearly extinct, with the remaining survivors forced to band together to flee the Cylons - a race of sentient AI. The Cylons happen to be the reason humanity's nearly wiped out and they intend to finish the job. There's also the tiny detail that the humans created the Cylons in the first place.
In the game, you control the human fleet and each turn sees the fleet trying to make hyper-space jumps to get away from the Cylons. With each jump, the fleet gets closer to either salvation or annihilation,as when players make a jump, the jumps will eat a precious resource: fuel. Lose enough fuel (and population or food) and it's game over.
To make things even more complicated, each player is dealt a ‘loyalty’ card. The card will determine whether the player is siding with the humans or, gasp, is a Cylon in disguise.
In some cases, forcing a player to reveal his or her loyalty card will result in Very Bad Things (TM).
So it's a hectic game where you will constantly be wondering if you can trust your fellow crewmates or, if you're a Cylon, you'll be happily trying to screw your fellow teammates over without getting found out. This game can either be mad fun or leave you wanting to murder all your fellow players. Consider yourself warned.
