i was wondering.. we always played that helo for example can use his ability only on his turn, meaning when he draws cards and gets a crisis card.

now cylons who reveal themself end there turn immediatly. if a cylon reveals as the first action of an executive order, the second action cannot be used (faq: the turn ends)

my conclusion now is that helo can get XO´d, launch a scout and reroll the dice?

You had it right the first time. The re-roll is only available on Helo's turn (ie - when he is the "Current Player").

On the other hand, if Helo XO's someone, and that player plays a Strategic Planning, Helo CAN use his re-roll because it's still his turn.

this would be true if not for this entry in the faq:

Q: What happens if an unrevealed Cylon is targeted by an “Executive
Order” and reveals himself as his first action.
A: He would be unable to take his second action. (Following the
“Revealed Cylon Players” instructions on page 19, his turn ends
after revealing). The current player then continues his turn.

so what makes you so sure about it?

I'm not sure what that FAQ entry has to do with Helo's ability... Ninja is correct, Helo can only reroll on his own turn... and yes he can reroll ANY die rolled by any player during his turn.

Right... that FAQ entry is only meant to tell us that Cylons can't use the second action if they reveal on the first action of an XO. The use of the word "turn" in the explanation isn't meant to indicate that ANY player who is targeted by an XO should be considered to be taking their turn. If you interpret it that way then you are reading WAY too much into the wording.

(I sypmathize... I still maintain that a strict reading of the Command location says you have to activate 2 different vipers... but after failing to find a single person who agrees with me on this forum I've come to accept that I guess that's not how the designers intended it... )

I agree, but I've never forced the argument in any of my games.

For fun, let's compare Command's text with the new Basestar Bridge:

"Action: Activate up to 2 unmanned Vipers."

"Action: Choose 2 of the following abilities:"

So according to most players, whereas you must distinct abilities for the basestar bridge, it's okay to choose the same Viper twice. If that's really what FFG intended, it should have said, "Twice, choose and activate an unmanned Viper."

Yes! Someone agrees with me! I still think it's intended to mean "2 activations," but I wish they would have said that explicitly, since even the FAQ doesn't really come out and say this (it says "the same viper may be activated more than once in a turn" or something like that, which isn't exactly the same thing, but I guess I know what they meant... uh oh, there's that "turn" word again!!)

As for the Basestar Bridge, it is spelled out clearly in the rules (Exodus p. 12) that you can't use the same ability twice on the same action, so I'll give that one a pass...
