WOP is ganging, the drones are all hostile, the humans are the icons with either an American or Japanese flag. The humans who are flying airplanes from the same country as yours come from are purple and show up as green on the dar. Killshooter is off with the idea being that it is a free for all although some people are inhibited at shooting at purple. It is confusing. Everyone is trying to get you and each other, the drones shoot at each other. I assume part of the reason for killshooter being off is that if you are flying a p40 and want to shoot at a human player in a p40 that is the only way to do it as if your flying a p40 there will be no red p40 that isn't a drone.
