I have read stuff on this before. But none of it holds up or makes sense. I played last night. Before the round I had a shield with 3 hash marks and the skull. Me and a buddy played Tranzit. We were messing around on the round not really trying to kill zombies. Running into the cornfield exploring areas of the map,stuff like that. We did not kill a SINGLE zombie. We lasted one round. We both leveled up. I checked my emblem after the round. I had 5 hashmarks and the Skull had glowing blue eyes. I have never been able to get the glowing eyes. Even when I go into the high rounds (in the 30's) and get lots of kills. Does anyone know how this system really works?
