So the gist is that you can see enemies on the minimal through harbors bubble.

Doing this is pretty simple. All you need to do is break the bubble. When the shield goes down, but the smoke is still up, the game seems to assume the smoke is gone too. This means that you are able to see enemy locations on the minimap even though you can't actually see them on screen.

I personally don't have the reaction time or skills to use this effectively but I think it could be used to cheese some key picks and flee.
