I think I see the confusion.  Did I not make it clear that the wall that has to come down is in the building where the gangers are?<br/><br/>Let's say that the teleporter put you down in a spot close enough to the wall, which wouldn't be too difficult to do stealthily until the wall suddenly disappeared and the light started coming in from the side of the building.<br/><br/>So far as I can tell, most Attributes don't require an action unless it's either an attack, using an Item, or has the Activation quality.  Picking up and ready a sniper rifle, though, would be a general action, so I'll count that as one of your actions and the first attack (the 13) will get through.<br/><br/>Oh, and I forgot to mention, but ACV and DCV cap at 9.  That means that the accuracy bonus on the sniper rifle would bring it up to 12, but the cap is 9, so it doesn't count.  If you want to move those points, let me know.
