Online gaming especially the multiplayer experience is something that should be savoured and shared by everybody and not ruined by cheaters. And there new game "Uncharted 2: Among Thieves" is not immune to this. And it is this idea that 'Naughty Dog' has implemented a system to stop these people. They will have players in the game which will monitor gameplay, watch message boards and report cheaters. 'Naughty Dog' has stated that the only way to implement this measure, in addition to overseeing online games is thru eternal vigilance. We can only hope that other developers follow in this example.
