Imho no wonder PvP in this game is an afterthought, if cheats like that work they got some serious security issues with their game. This video makes me think of other things as well, if wall/memory hacking is possible then how do you know people aren't using this to exploit other content. A simple thing that comes to mind is duping expensive stuff to sell on the MB.

I really do hope there's some security in this game otherwise this is a joke.
