Etkey File Generator

Press the "Generate" button to download an etkey file. Copy the file to your etmain folder. The file name has to be "etkey" without any extension.

Depending on your operating system the location of the file is:
Linux: ~/.etwolf/etmain/
Windows XP(seriously get an upgrade): etmain folder, where ever you installed the game.
Windows 7: User/AppData/Local/Punkbuster/ET/etmain
