Hahah I just posted the same thing a few seconds ago.

Now that you put it this way, it sounds more like a glitch where as I thought it might have been intended for players who prestiged

However the people I have seen using it have always been the opposite colour - orange if on my team and blue if on other team. Keeping in mind that I use colourblind assist it should be the other way around.

This is not a glitch, its a perk !

Its called, Friend of My Enemy ...

Standard version: Makes enemies see your name as friendly rather than enemy.

Pro version: Makes people enter Call of Duty Forums and complain about it being a glitch/hack/not being fair ...

LOL, jokes guys!!! Seriously, I'm just having fun ok. But yeah it does sound quite annoying.

It's going from bad to worse, clan tags and now this.  That was very funny South Auckland, like it.

Saw someone with a purple name in a lobby, didn't even bother playing them, reported and left lobby.  There's a key to getting these people banned, report in the game and through their gamercard. 

It also helps in the short term to avoid them.

Will destroy hardcore

hex edit over usb = security fail....

Fully agree.. it also shows all those guys that said the clantag wasnt an issue... we all said it was only a start of worse to come... if people will do 1 glitch they will try them all!!

This is gamebreaking - this will kill Hardcore.
