Nightwing "Bowled Over"
Ok... I really have no idea how to get Nightwing's "Bowled Over" to work in Black Mask's Predator Map (Robin's Pack).
I have snuck up behind henchmen on the walkway and used the electrical blast but it doesn't give enough force to throw them over the walkway.
The last guy I tried was actually leaning over the edge pointing his gun downward looking for me.
