Example, a ship receives a critical hit and flips Munitions Failure: Immediately choose 1 of your secondary weapon Upgrade cards and discard it. However said ship has no weapon Upgrade cards. How do you resolve this?

Is it simply converted to a normal hit?

Logic would dictate that a ship can not suffer a critical hit to a system it does not have. So possible resolutions:

1) Draw another critical hit card in place of the one that can not be resolved (continue until one that can be resolved is drawn).

2) Take an additional hit in place of the critical effect (totaling two hits).

3) Roll an attack die and suffer any Hits or Critical Hits rolled as additional damage.

Other ideas or ruling? (did a board search but couldn't turn anything up)

If it doesn't apply to your ship, consider yourself lucky, as it's just a normal damage then.

Flip it over as per the card's instructions and carry on. After breathing a small sigh of relief at your good fortune.

Never mind, too much typing for this late.

Chalk it up to "Luck of the Draw"

You just grin evily at the other guy and carry on.

Unless you're flying Super-Dash, with 4 hull left vs a 1 hull Soontir who is at R1, Soontir fires first and deals the above crit and a damage, and you grin broadly as you now get to fire back - and you then manage to kill Soontir.

This happened yesterday. We couldn't stop laughing (after I cried a little, as it was my Soontir )

My favorite is getting the "turn your hard turns red" on the shuttle

Why thank you.

Injured Pilot on an Academy TIE is also fun. "Oh my god I'm hit ... and I feel perfectly fine, carry on!"

You resolve it normally. A ship does not need a Secondary Weapon for Munitions Failure to resolve normally. Maybe the crit doesn't hurt the ship as much as you'd like but that's the target getting lucky. Your "resolutions" are just horrible for the target.

Is it simply converted to a normal hit?

Technically no.

You do not convert it to a normal hit. You do what the card tells you to do, and only what the card tells you to do. Even if it seems like you can't do it. You still process the text of the card. If it instructs you to do something you can't, like removing a secondary weapon when you don't have one you would still check then move on to the next step, in this case turning the card over.

But if you have a Structural Damage card on a ship with 0 agility you don't turn it over or ignore it. It's still in effect even if it's not doing anything at the time.

Why thank you.

Mine is Farlander getting "receive a stress token" from a ship he's about to shoot.

Why thank you.

I've also seen that one crop up on Fel, who was then attacked a second time for lethal, and he used the bloody focus token to survive!

Do what the card says, and not what it doesn't say.

Thanks for the replies. We have been playing with just flipping the card over and the target it chalking it up to a "lucky day". As to the options I presented - they were just spit ball ideas, tough on the target but logically applied. There are numerous similar games that have this sort of "shifting effect" mechanic if the resolution of a hit is not possible. One example is suffering a observer or tail gunner wounded result on a plane without, it then becomes a pilot wounded effect since there was no target for the effect to be placed on. Again they were thoughts that my group has been having on it and we are likely to adopt one of them as a house rule for the situation, I just wanted to hear from the community at large to see how it is being played out. Thanks again all.
