Their career combat record stats.
Give-a-ways:
1. Score per minute of 1200.
2. K/D 2.0 or greater
3. Total days played < 7 or 8.
#1 Obvioulsy is a dead give-away. I saw this on a kid last night.
#2 I know there are good players around that may have this legitimately but, not one or two in everygame. Especially when they consistently score a 1:1 or less in the matches you play with them. I have played with some really good players that are consistently at the top of the leader boards that have hacked their prestiges (and admit it) but they don't get the huge ratios that a 2.0 or higher would require ALL THE TIME.
#3 I'm not a great player. MY K/D is only 1.02 and rising (and I blame this partially on lag
) But I have 8 days played and am only at Prestige 5. I mostly play TDM or KC so not as many points as other modes. You get the point though, and I played nearly the whole weekend double points were being given.
