Ok, so software developers spend millions of pounds creating and marketing a game and you can't be bothered to shell out �30 quid for it??
But anyway, yes, www.suprnova.org (the "e" is purposely omitted) and Newsgroups offer extremely fast download speeds.
You will need a bittorrent client to use suprnova - just google bittorent. It's really easy to use and it's completely free. If it asks you if you've donated just click yes and you'll never see the pop up again:-)
