Four billion player kills in one year is quite a feat, especially for a free-to-play FPS.  Well, Combat Arms is still pushing that figure and has gotten its 16th map now with "Grave Digger."

A new trailer showcasing the map was just released, composed of compiled gameplay footage. 

On top of the previously announced four billion kills, Nexon also noted that 1.5B grenades have been tossed, with 240 million hitting their mark.  Ah yes, only in the gaming industry would you brag about having wracked up billions of deaths.
