Just have to wait for the game to come out then.
I got the full beta in mid June from ftp of some guy named Blaze in the mirc channel irc.easynews.com, sub channel #ut2003. His ftp like others are long gone. And that channel is so dead, I never see anyone asking for the leak there anymore. But maybe try and ask them for it, if they are even awake, it's not an official channel of the game, far from it.
Peer to peer of Kazaa-like places is supposed to have it , but I don't know Kazaa very well. I'm getting borderline now, so that's enough for awhile.
oh dang, forgot, I do play it online and it looks so cool, sometimes get 8 to 10 players. List of active servers, click on the Servers tab - http://www.reality-check.tk/
Is that site going to far?
