I feel that everygame I will be playing with these people and also for no apparent reason. When we are winning and owning the enemy. They suddenly have harrier pavelow and ac130.

How do we deal with these guys because I reported and nothing is done

1. Ask everyone on your team to go spectator-mode (hence, leaving the cheater no targets to shoot at).
2. Leave the match.

I played mw2 multiplayer and let me tell you its full of hackers everywhere. like you said.. they can shoot through wall wth

or maybe u just sux at it?

Pro player can still beat wall hacker.

in a sense yeah, however there are times you are labelled as a hacker. That happened to me when I sometimes get 30-4 K/D ==""

But at the cost of his usual kdr...
