I am not much of a gamer, but my little one loves World of Padman, which is playing suprising well in my mode Radeon HD4350 with the open source driver in Kubuntu 10.04

Long story short, when he goes online to join a game server, the game starts downloadin custom "worlds" or "maps" or whatever that is, in the form of pk3 files. This process takes forever. And the ubuntu binaries come with a bunch of standard pk3's, but it seems that in most cases we are missing some. Is there a simple tarball I can download somewhere to have all possible pk3's so I he can actually play the game? Believe me, I googled for this

Thanks a lot for any help!
