So, Theres this release for this game, its a quake3 game (Urban Terror) and i need to know if we will download the release in a .pk3 file or in a whole new client? ( The update is new weapons, animations, etc.
While I'm not familiar with Urban Terror, I am familiar with Quake 3. In my opinion you should grab the .pk3 release and stick it in the folder structure manually. You will probably find that the client release will require Windows to run.
