I thought there was some kind of anti-chat patch?

I just went into chthulu's server, arguably the best server on gamespy, and you cant play cause someone is cheating.

Basically the moment you spawn like 6 german nades go off at the spawn site, then some guy appears WAY BEFORE the best German spawn site could have gotten to the end of the allies spawn site and he shoots people. He does not come from the front, he appears BEHIND the americans.

WHAT THE HELL IS THAT???

Why ruin the game for everyone else? There is no skill or power in that stuff. Just a waist of time.

How did they do this when there is suppose to be an anti cheat patch?
