So this has already been posted before. But sometimes it messes up and you can kill due to the fact you cant reload. So im going to tell you a easy way to fix that.

1. Have a server up.
2.open cheat engine and hit the computer icon.
3.Select client.
4.Look at the number to the right or how many bullets you have for reload. (i think it is how many bullets you have left)
5.Type that in on the scan bar. And then hit first scan.
6.No there will be alot of numbers so you shoot then reload and type that new number until there is only 1 number in your list.
7.double click that last number. Until it is in the pig box down below.
8.Right click the number and select. Change record then value.
9.Change it to what ever you want.
Hope it helps. My issue was that when I shot over 30 bullets they didn't kill anything. If that makes any since. IF you need any help ask me.
