Despite the fact that Halo: Reach wasn’t even released yet, pirates all over the world are downloading the game right now from BitTorrent sites.
This was due to Xbox.com hading out codes for reviewers, and a group of pirates managed to get those codes and put the game for download.
Videos are now popping up all over youtube, showing gameplay and many story related (with spoilers) videos, so watch out.
We will see how Microsoft will react to these videos.
