Click on Combat Arms hacking section and scroll down to the lines w/the envelope looking signs and click on the [Release]. there you will find a post, scroll down to a square add and the download should be under it in blue. It will either be .Zip or .Rar (Winzip, Winrar). Download it and inject it into Combat Arms with either perX or FInject you can go to google and search it for a free download. Inject it as Engine.exe and browse the hack. Then you can set it to automatic inject and just start combat arms and you will be off to hacking!
