Up until yesterday, I have been going with the conclusion, just like everyone else playing X-wing, that wording on both TLT and CLUSTER MISSILES meant that you were performing two separate attacks with the said upgrade card. This is not the case. The wording on each card says:
"ATTACK: "Perform this attack twice".
In both cases, the card represents one(1) attack with the performing all of the steps involved in resolving the attack and repeating those steps a second time. This does not mean you are doing two attacks, but rather you are doubling the outcome of the one attack.
A TLT attack is one firing of twin(2) laser cannon beams, each beam being a 3-dice roll. You roll for the first beam, applying all steps in combat then roll again for the second beam and repeat the process. The total is the final result of the one attack.
A CLUSTER MISSILE attack is the firing of one cluster missile that breaks down into two groups of three submunitions. You roll for the first group of three, applying all steps in combat then roll again for the second group of munitions and repeat the process. The total is the final result of the one attack.
-----------------------------------------------------------------------
Now with this in mind, say you are involved a simultaneous attack with an opponent and you have TLT/CLUSTER MISSILE and GUNNER. If you have the initiative which result is suppose to occur?
#1) You miss with the TLT/CMs first roll, opponent gets to make his attack. If you survived, you complete the second roll (the end result doing one damage). Then apply GUNNER ability because you missed the first roll to the same or different target within the arc (or you dont because the second roll resulted with a damage).
Or
#1a) You miss with the TLT/CMs first roll, then apply GUNNER ability because you missed the first roll to the same or different target within the arc. Opponent gets to make his attack. If you survived, you complete the second roll (the end result doing one damage).
[This is the current situation with the rules in determining that TLT/CM cards actually represent two separate attacks]
#2) You complete both attack rolls from TLT/CM, opponent gets to make his attack. If you survived, then apply GUNNER ability only if both previous attack rolls missed, to the same or different target within the arc.
[This is how I interpet both how the TLT/CM cards work and the fact that GUNNER ability is counted as a separate attack and would have to go after the opponent made his simultaneous attack.]
#3) You complete both attack rolls from TLT/CM. If both rolls miss, Gunner ability kicks in and chooses which target to fire at. Afterwards, opponent with simultaneous attack goes.
[This could occur if GUNNER is meant to "immediately" follow after the TLT/CM missed completely. Note GUNNER can still choose between targets]
Which outcome is suppose to happen?
