By the look of this and his cover it is certain that he can block bullets, but he is only using the bubble on him so maybe he can't place the bubble other than protecting himself and his nearby ally
The dots looks like some sort of blind plus the water below looks like a trap so maybe its a trap + blind
The wall looks like it starts with less height but it gets bigger and bigger as it spreads, also from the cover of harbor it looks like the wall will act like astra's ult when we try to pass through it plus maybe some sort of distorted view
