People usually use Codebreakers or some dumb shit cheating program. But actually this time they worked with Gameshark to fight the hacking.

They've fixed alot of shit. Most of the wall hacks you see in all the maps are gone, I've only seen one map on II that someone got into the walls. More weapons, more maps, you can blow up the Claymores this time. They revised most of the old maps including Abandoned which is now at night. There's so much other little shet that makes II 10x better than I.
