The people asking for credits for each kill seem extremely stupid to me. that being said a nice way to distribute them for free would be with the medals you get at the end of each round, for example, accuracy, best KDR, most kills, and others. !00 credits for any of them would be stupid, but 5-25 depending on the challenge of getting each one at the end of the round wouldnt be unfair to those who pay to play considerin the fact that they will benefit from it more than a free person will since they have the advantge of already owning the better gear.
