My friends and i just played our first game of bsg last night, and it was awesome! But there was one thing we couldnt agree on, and the rulebook seemed to be a little short on the subject:

A player draws a cylon attack crisis and the basestar, raiders, heavy raiders, vipers and civ ships are placed the the board.

If another player draws a new cylon attack crisis, while the ships from the previous attack-card are still on the board, we agreed/disagreed to additionally place the new basestar, raiders ect. on the board as instructed by the card - so we now have a board swarming with all kinds of ships. Is this correct or should the 2nd cylon attack crisis card be discarded?

If it's correct that the board is just filled up with tons of ships, what then happends if a third cylon attack crisis card is drawn? We only have 2 basestars and they are already on the board. Do we just add the extra raiders, heavy raiders, vipers and civ ships?

...and now i need to go work on my cylon detector!

Yes, if another cylon attack is drawn from the Crisis deck you set up the ships on the board as much as possible. That means if a basestar appears and both are already on the board, then the new basestar does not appear. If there are not enough Civilian ships, vipers or cylon ships, put as many as available on the board, with the active player choosing which areas get the ships (which usually means humans put the cylons as far away from the civilian ships as possible and the cylons vice-versa).

Well, you played it right for the most part.

Attack Crises have three steps on them, 1. Activate ships, 2. Place new ships, 3. Special rules, and they should be done in order.

So, if you draw an attack crisis and there are cylon ships on the board, you should activate the existing ones listed in step 1 before placing any new ships from step 2.
