Play JK with new features:

- Addon Organizer: Place all of your downloaded mods and levels in one folder (or set of folders), and let this program handle the details on how to run them.

- In-game Chat Window: Use the new in-game chat window instead of the hard-to-read default one.

- JK Lobbies (like the MS Gaming Zone): Connect to the Hub's server and host a game that others can see, or join in someone else's game.
