Guess they really anity there security took them 4months.
There security sucks look at all Infinityward games COD4, MW2, MW3 all the best mods are on Infinityward games I doubt they just now realized how to make cheat system for a game that's been out for 4 months and in development for over a year.
They probably called Treyarch to come in and add an anti cheat system...
