As clearly seen on Hellspider's thread that he released Xtrap does not work on official servers that use the heartbeat packet. So we can assume unless your on a private server this will not help you.
He also states that it does not bypass Gamegaurd meaning that even if it did work on clients such as the NA (usa client) that you could not inject codes using Cheat Engine(or other such tools)
Assuming that you are on a private server ( such as elite cabal) than he has a simple tutorial on the link provided at the top of my post.
The real question is:
Where the hell can we get an NA(USA) unpackedmain.exe and game guard killer.
So we can do the easy part on our own with CE.
