"A Gate, two Birds and the beautiful Sky" (GBS) is a high Quality modification for Ritual's Elite Force II. The Mod is open source and has been touched by many legend ef2 Modders.
This program will patch your EF2 main executable, so that it will use the new community Master Server. You will then see Internet Servers inside the game again.

Unfortunately the Elite Force 2 masterserver, which was provided by activion, is down.
This program will patch your EF2 main exe, so that it will use the new community masterserver.
You will be able to see Internet Servers again in your in-game Server-Browser.
After patching EF2 you may run it als usually. Please consider, if you use any FIREWALL, that you will probably have to reallow the internet access for the ef2.exe/quake3.exe, due to the changes which have been made!
