I didnt find a direct rate, but it tells you your overall kills and deaths.
Go to Warzone, and then from there, im not too sure what the Menu was, but im sure you can figure it out, and then if you find it, there should be another sub menu called My Statistics. At the top [It begins to auto-scroll downwards], is your total points, kills, deaths, headshots, etc.
Yeah I know about that, I was just wondering if it showed an actual rate. Oh well I guess I'll just have to figure it out myself. Thanks
Edit: Ahh I found it on the killzone.com site. Mine is at 1.43. 904 kills and 632 deaths!
