Hey Silencer, thanks for taking the time to look at my suggestion and letting me know the limitations of the API. I think Klypto is on the right track with the support Ribbons. It's not perfect, but it is something.

I had another achievement idea, it would be hard enough to get that I think it really classifies as an achievement:

Smooth Operator - Get a mega kill (maybe exclusively with headshots) with a bolt action rifle

Since bolt actions only have 5 rounds in a mag it would mean getting a kill with every shot, back to back, without reloading.
