Counter Intelligence

It may be played this turn, as it would normally be played by spending HQ, .

So yes, you need to spend HQ.

Hi,
for this 2nd card and in the turn you choose it among the discarded combat cards : is-it necessary to spend its HQ cost if you want to play it immediatly ?

I suppose Yes.

Yes, that's how I read it as well.

This seems to be a card that allows a 2nd Combat Card to be played in a turn. So an exception to the rule of only 1 Combat Card per turn
