So Crytek may have done a big fudge up when they were designing the MP of this game ...
What you see above is a video of PURE rampage being done to players by some one who ISN'T using any hacks of the kind all he did was a few client side tweaks to a few files in the game directory, he manipulated the energy, nanovision, damage and speed and as you can see the result is ... well a really over powered individual handing out punishment on a silver platter so far this hack is possible on PC and will probably spread to JTAG XBOX 360 and Jailbroken PS3's.
But I just have to say this ... GOD DAMN CRYTEK what have you done? I mean this is really embarrassing. I hope Crytek manages to fix this in the future before it gets WAY out of hand.
For demonstration purpose only. Crysis2.exe was not hacked. No external hack application is running in the background. Just a few tweaks client side.
