Here is a channel you should subscribe in Youtube if you play COD.
The link is as below and he just uploaded a game play a couple of hours ago.
According to him, his best so far is 55 kills.
I watched a few of his game plays with ASM1 and I found our style to be quite similar. Maybe that is because we were both using ASM1.
But off course, he is a lot more better!
