Here are the complete instructions for Windows 7/Vista users.
1. Unrar it using WinRar (google it).
2. Rename the injector and the .dll to the same exact name. I simply used 's' without the parentheses.
3. Right click the injector and select 'Run as Administrator'.
4. Run WarRock
5. Have fun
To navigate through the hack menu, simply use your arrow keys. Left and right to turn things on or off/open different menus. To hide the hack menu press 'Insert'.
Any other questions?
