Say you have Experimental Interface, and you get hit with a selection of the following Crits.

Loose Stabilizer
After you execute .....
Action : Flip this card facedown.

Major Hull Breach
Starting the round after .....
Action : Flip this card facedown.

Console File
At the start of each .....
Action : Flip this card facedown.

Since the action words are exactly the same, (just like say, performing a free "barrel roll action") is this subject to being in effect the SAME action? thus you are unable to action both cards in the one round using EI?

Damage cards are NOT Upgrade Cards and thus not legal targets for EI. You could use the Action performed from the damage card to trigger EI but you would have to pick an actual upgrade card's action to perform.

Now if you had multiple actions that could target Damage cards you couldn't target cards of the same name but you should be able to target multiples that flip the card face down. The "this" in each of those cards is different.

ahhhhh... cheers StevenO

What about if they were Coordinated from another ship? Coordinate is just a free action, not limited to action bar or upgrade card? <- I think you answered this with Part 2

They are not the same action like StevenO said. The this is not the same for each card. But you could not flip two Console Fire.
