BitTorrent is a very popular P2P file sharing system, if you are not familiar with BitTorrent please take a moment to read this guide and familiarize yourself with everything there is to know about BitTorrent.
As with any other P2P system it relies on you uploading data to other users, so please after your download is complete leave the torrent open as long as possible so other Tekken fans can get the movies as well, there is no point in further developing the Tekken Zaibatsu torrent tracker if you 'grab and go'.
