I really think there should be some measure of veterancy. It could be in lots of ways and frankly, I am not decided on how it should be.
It could be in the simple form of some sort of score. A tally of Zeds killed, Survivors killed, and maybe even healing actions undertaken.
It could be with the old Hero/Bandit skins.
It could be with a bit of a 'toughness' perk.
I don't know. I just feel that staying alive for several hours/days should show some sort of reward. I should have more to show than a fresh spawn.
What say all of you?
