We are offering all KF players and server admins the chance to join an Open Beta Program for future changes to the game.
The first features to be tested include Surround Sound support for Vista and Universal Plug'n'Play Support for Hosting Servers, as well as a new map white-listing system that will allow us to update the white list far quicker than before. This beta also includes exploits fixes on all the stock maps.
The Beta Program is now available to all. To take part, individual players can chose to opt in to the Beta by changing the Beta Participation option in your Steam Settings. Server admins can opt-in to the Beta by running the hldsupdatetool with the following command line addition: -beta Kfwebwhitelist. Please remember that this IS a Beta program and that you will only be able to play with players/on servers that have opted in to the Beta. You can always opt back out of the Beta at any time and restore the original version of KF.
