HURRY UP and fix the hacker problem!

Its pretty damn clear when you are playing against a hacker, constant head shots health never drops below 50% and on 2 occasions now I have seen players going into the walls to hide. C’mon Gearbox i am a massive fan of your work but it is getting past the stage of being acceptable in a game you really need to get this fixed. Is there no way you could work with Valve to get the game introduced with the VAC system?
