I'm not quite sure how to go about it. Do I have to take a usual hunting action against a creature from the hunting deck and subtract 5 from the weapon value plus what's written on the animal card? As an example, for the tiger,I would have to remove 7 (-2-5) from my weapon value...?
Nope, you just assign 2 pawns to the special hunting action area on the scenario sheet and resolve this action by decreasing your current weapon level by 5 (taking wounds for each lacking level) or by 1 if you already built the tranquilizer. If you survive (and actress is not captured, and director is still alive), you win !
