According to numerous reports, release group "iCON" has leaked the PAL Xbox 360 version of Grand Theft Auto IV onto a number of torrent sites. It weighs in at 6.32 GB and appears to be the real deal, with unscrupulous individuals now posting gameplay clips on GameTrailers and the like, which will no doubt be swiftly taken down by Take-Two's legal team soon.
If you do happen to have a modded Xbox 360, we hope that you can wait six more days to purchase the real thing and not resort to illegal activities.
