Well, beta 1 has been out for a little more then a year and has died down because it was a little buggy and there were a few game play issues that made it not as fun. Beta 1.5 however, is coming out sometime soon hopefully and that should be the return of many players. However, usually if you download goldeneye source beta 1 or beta 1.1h (unofficial), there is always a handful of people that play during certain times of the day. You just gotta keep checking. And the servers usually house about 10 people at max per game sometimes more or less. It is a fun mod man, along with a BUNCH of other ones. If you would like to know some other FANTASTIC mods, just pm me.
I suggest downloading beta 1 and then patching it with the beta 1.1h patch that the developer Lodle made because it fixes many crucial bugs that made beta 1 difficult to enjoy. After you download beta 1, you can download the beta 1.1h patch here:
