On occasion Punk Buster may release an update for a specific game.In this case, the game will usually kick you from servers if you are running an old version of Punk Buster for the game.

It synchronises with Windows Control Panel to use your normal Windows speaker layout, or some variants (such as 3D7.1).
You can use automatic settings, or configure it with our setup software before using the other Rapture3D components: work on mac OS.
To update the version of Punk Buster for a specific game, download from their website.
If the game you want to update isn't listed in the main view, select Add Game and find the game you are looking for.
