Well i managed to get 5 kills in a row without dying with the ballistic knife. Was able to do them both in the first 2 games after i got home from shopping. Funny thing is that i got the ballistic knife master card and gold camo after i only did it once. So I had gold camo but not the skull camo. I had the gold camo for the SVU-AS sniper but not the skulls for that either, but it somehow looks like it fixed itself.
Glad i was able to get the gold for ballistic knife, because im about to prestige, but i can prestige and then use my free token on the crossbow, since i will have the combat knife from the start. I still need 4 kill enemy with combat knife.. then again with the weapon they drop. Also need to get 4 blood thirsty medals with combat knife. Its kind of hard, but once i get 2-3 kills in a row i try to camp with shock charges so i can stun them and then rush and stab them.
Oh and here is my new emblem... Lag Ops II wasnt cutting it anymore.
