Now if you guys are that worried about ghosting I can make it so that they will not be able to see when dead while playing from the same ip at the same time. However I find this to be very annoying which is why it is not on by default. Or we could do it another way and if the players in question agree I could make it only effect just them and only when more than one is on at a time.
