Berlin Apex Predator
When you trigger the tower lasers and make Agent Termain (the sniper) spot you, he will try to shoot you. I thought it is limited to the tower area.
But once he started shooting he will get back to his rifle everytime you’re in line of sight (Even outside the tower on roofs and the containers). When you’re not in line of sight, he changes to binoculars. Are you back in line of sight he goes to the rifle and starts shooting.
So i used that fakt to make him kill Agent Green and then himself
