This might have been answered in another thread, if so im sorry for asking again.

But if i have lets say XX9 TL and Proton Torps on a shrimp, and i roll 2 Crits, can i use one crit to activate Proton Torps, and then XX9 states that the first 2 crits i roll are faceup, thus giving me another faceup, if i punch through the shields?

And sorry i misread the card...it all makes sense now.

You cant. as you can only activate one Crit pr. attack, and the XX9s need a crit to work to.

Nope.

The number of crit results that you get do not matter for resolving a crit effect, only that you have at least one. As long as you have at least one crit result on your dice, you can activate one critical result. That means you can chose EITHER the Proton Torp crit effect (one face up damage card), the XX-9 crit effect (first two damage cards are face up) or the standard crit effect (first damage card is face up).

You cannot activate multiple critical effects on the same attack.

Edit: Check out this video for the order crit effects happen.
