I'm strongly considering resetting my stats after I prestige. Does anyone know if you keep calling cards? I don't really want to give up Ultra Killer.
You lose everything..
That's what I figured. I never thought I would earn Ultra Killer and did it on accident one game on Hijacked. That's the same reason I used the title and emblem I had in Modern Warfare 3. It was for killing someone with a flashbang.
