is there cheating on this game or am i really bad?

I've wondered about some of those scores as well, but maybe some people who've worked on the game know exactly where to go can streamline in 30 seconds, it does make you wonder though.  I'm sure the leaderboards need to be tested out just like everything else, and perhaps someone sets the bar really high before the game even hits the streets.

its not possible to kill 9 guards all armed by stealth or any other method in 30 seconds,theres definatley cheating going on.

its disturbing that so many games are being hacked in some way this is what you expect from playstation not xbox

Stop being so paranoid, people. Some of the gamers on that game are just AWESOME. If you search on YouTube, you will find some really insane times for each predator level. Like this one on Silent Night.

A lot of score are fakes made by the game's makers. Many times u see a person and it say's they haven't played the game. If that score board gets reset then it was hacked if not then the devlopers put the score in as fakes so no one can really brag or they scored them while testing the game.

There's another thread here, by Lord BaneJ, where there's an in depth breakdown of the scoring system and I can see now why some of those scores are so high, check it out...:-)
