Let's say you are behind a nice plasteel wall and don't want to come out to get shot. You stick your periscope equipped gun around the corner to start shooting.

1) are you still in total cover, or are you not 100% covered? Guns like corner shot (which I think is what a periscope is supposed to act like) can be shot without exposing the shooter at all.

2) are you enemies still blind firing if they see your gun sticking out? I suppose they would have to be guessing at your exact position, but is that really worth -6?

3) are you unaware of the incoming attacks if you can see them via imaging device?

Total modifiers if this all works would be -6 to the attacker, attacker has to break through the wall to do any damage, defender gets full reaction + intuition +4 to defend, ties go to the attacker, defender can return fire at -1 with a wirelessly enabled periscope (-3 for other imaging devices).

Average Corp security would have 2 dice left after the -6, making even a single hit tough. Then if they can score a hit you get to defend at +4. Even with a pretty bad 6 dice for rea + Int, that jumps to 10 dice. 3 hits ensures it is impossible for him to even tie. 2 hits on defense means he has to roll a success on both dice (it happens sometimes). Finally he compares his damage to the armor of the cover (if he managed to hit), and is likely rebuffed. If he manages to get through the cover by some miracle, he does his DV -1 for shooting through the barrier.

All in all this feels super strong (maybe even broken), but would totally play up the positioning aspect of modern combat. Finding ways to expose flanks, ignore cover, or change the conditions of the field would be super important. So on the one hand it feels to good, but on the other it feels very thematic.

Do you run it this way or treat combatants behind full cover as unaware, even if they can see their target (imagine one way ballistic glass where one side can see out while the other cant see in)? Is the fire really blind if they have a position indicator such as an exposed gun? How do you rule it?

If the Defender uses a Take Cover action to get behind something where more than fifty percent of the defender’s body is obscured by intervening terrain or cover, he gains a +4 dice pool modifier to his Defense roll against any attack.
Note that this modifier does not negate the Blind Fire modifier the attacker suffers. Both the modifiers to the attacker and to the defender would apply when firing at a target that is totally concealed (one hundred percent behind cover)

I use this in combat.

A defender using the barrier as cover receives a defense bonus for cover. (as above) If the defender is completely hidden behind the barrier, the attacker suffers a –6 Blind Fire dice pool modifier for not being able to see his intended target, but the hidden defender is considered unaware of the attack.

Then leave this for situations where the defender is waiting in ambush or otherwise not moving, *and* the attacker is precisely aware of their location.

Core pg 176-177 covers that. Attacking from Cover with an imaging device. Whether that's a gross eyeball in your hand, or just a Smartgun since they all come with cameras anyway. Either way, it's only a -3 to your attack.
