"Yes, there will be spotting," Alan Kertz. Spotting is when players can highlight an enemy for the rest of their team, placing a red marker on the player which is visible on minimaps. The DICE team want to improve it with the third dimension?
"2D spotting is a minimum," he added. "I want a form of 3D spotting that avoids, 'There, behind the tree.' 'What tree?' I want a balanced 3D spot that works for a whole team."
