lol, CoD2............ that was good
And ya, it does run a bit too fast, but its still pretty good, Most games now are fast moving games. But if you get a squad and you get into the matches (coordinate your selfs) then it should be a pretty good, match... I mean even if its a Team vs Random players it would be relatively slow..
And as for hackers, there has been no update yet, and with most new games w/ no updates there are flaws that were not found in the orig testing (because they did not test for hackers

) So ya.. just give it a bit of time, then they will most likely fix that. ( I have not ran into any hackers, you can hear foot steps and with UAV's see where they are around corners)
