You're going to need winrar, a .dll hack, injector, netframework, and several other things that you may already have. I recommend using portal injector. all you do is make a folder, put the hack in it, and run portal and it does everything for you. Most injectors need to ran as administrator and you may need to disable your anti-virus / firewall. When you inject the hack make sure you always pick the process "Engine.exe" without the quotes. If, when you try to inject, it has a problem about something about a .dll then type that exact dll into google and download it, open your combat arms game folder and just drop it in. These are pretty much all the basic steps to hacking combat arms. If you still need help just message me.
