5 player game, someone starts as a "secret" cylon. I'm guessing you suggest ideas that would be weaknesses for humans. For example, "lets work on hull strength" when you plan for cylons to attack engines. Mid-way through game you draw another card, and someone else will become a cylon that didn't know they were a cylon. So it will 2 cylon vs 3 human players. there are objectives for humans to win 1st place like you can be elected president etc.
