Resistance 2 HELP!!!

For those of you who have managed to aquire the Killing Machine Gold Trophy (10,000 Kills in multiplayer), can you tell me how long it took you to get it and a rough estimate on how many game rounds you had to play to aquire it. Im roughly around 2500 kills and im a pretty impatient guy.

lol, Too bad you're impatient, because from what I hear, you're in for quite a long wait.

LOL ya i know, this could take a while, I just want to know how long i have to suffer for:)
