injector

I have no idea how i can use injectors and wath to do with them and also the .dll files i have no idea how it all works plz help me

First download an injector
Run the .exe file
add a dll file, can be downloaded from a hack thread
set the process to inject as engine.exe
set injection to automatic
run combat arms
hack

If Your Looking For An Injector, Use Perx (Google it)
Or Look It Up On Mpgh.
