BFBC2 has no hackers as far as I know, I personally haven"t seen anyone hacking. EA games are server-sided which means it'll be a lot harder to write a real time modding tool or any other hack especially on console. It's more that I think a lot of people boost to get in the top of the LB. BF3 and BF4 had small tools which gave unlimited ammo and could change your name, never seen a working godmode (maybe private tools have tho) but EA patched them very quick. I don't see BFBC2 having those since it's an old game, I wouldn't know why hackers would code tools for such an old game.
About Kim, I heard that as well, I wouldn't be surprised if he modded as well, CoD is not server sided and some coders release hacks before the game is even out, for old games like mw2 even someone like me can go to a modding forum and become top 100 leaderboards in 1 minute by changing my stats...
I'm just interested in seeing who played legit and who boosted in the time I was gone 🙂
