I dispise the new leaderboards, as I don't play public, ever. So I now only care about the icon next to my name which seems to record the highest round i've reached. And also the odd little quick revive perk I seem to have unlocked by performing 100 revives.

I would think that it amounts to the number of rounds that you have done? e.g. Single bone = Wave 1-5 Double bones = Wave 5-10 Skull = 10-15 Skull with Blue eyes = 15-20 Skull with knife = 20-25 Or something along those lines. I'll see if i'm right tomorrow, by making an account and just getting to certain rounds. Or if anyone else has the time to test it now, try it out.
