During the Combat Phase, instead of making a normal attack, you may discard this card to make 1 attack with your Primary Weapon and 1 attack with one of your Secondary Weapons. Each of these attacks is at -1 attack die and must be made against different ships.
1) What sort of cards are considered Secondary Weapon? Is it any card that is a [weapon] Upgrade and/or is it any card that has an Attack Dice value on the card?
2) Can Antimatter Mines be used as long as they overlap a ship (thereby making it an attack)?
