If you don't know how to inject hacks for Blackshot, follow this tutorial.
First, you have to get injector. I fully recommend PerX or Faith injector. I will use PerX injector in this tutorial.
You can get PerX injector at the attachment.
Open PerX injector and type "Blackshot.exe" in What to inject box. Click on "Browse" button and search for your .dll hack. Then run Blackshot and click on "Inject" button in the PerX injector.
