I'm going to go through some steps to help people with questions
Help! It's not showing in game!
The reason is you have to press B in game and select the hacked weapon you hacked. It does require BP, but it's better than using GS
I have a error! It says Weapon info does not exist!
This is because you might be playing on a global server, and not a server with P2P on it. To fully function this weapon hack, you must go to a server with the green H logo.
I'm getting weapon index error!
It might be the weapon that you are using. Some weapons are patched and will give you the weapon index error. Here is a list of working weapons that I have tested:

Rullof or Cod3rin has also created a thread called "Working Weapons List". Go to there!
EDIT: Also, I'm pretty sure this will only work for 64-bit users. Sorry 32-bit users.
