To Necro,
Does someone have an idea how do deal with that problem?
The Unreal Tournament 2004 Master Server was down last night. I haven't checked to day yet. If you want a list of KF servers, try going to x-fire. And I shall put up a list of the most common KF servers below.
1. Miasma server (KF252) - 174.34.144.162:2600
2. r2K Slaughterhouse server (KF252) - 85.14.227.97:7777
3. UTzone (KF252) - 85.131.217.246:8464
4. DHz server (KF252) - 85.214.148.241:7777
What to do to log in, open your KF, then click "Server". Then RIGHT click on "server name" then choose OPEN IP! Type in the IP address above of the server you want to join and WHAM. You're in!
