I know that killing an enemy on foot will give you more experience than killing an enemy by running them over or shooting them from a vehicle (related question here), but is the amount of experience gained dependent solely on the killing blow?
In other words, could I use the vehicle machine guns/rocket launchers to soften up a tough target, get them down to very little death and then pop out of the vehicle to land the killing blow and get the full on-foot XP? Or does it take into account the percentage of damage done on foot/in vehicle?
