In what appears to be a legit photo, this guy has a retail copy of Halo 3 long before it’s September 25th official release date. Reportedly a Norwegian game store has sold at least 2 copies.
This type of leak may be fixed in the future with a 0 day update, requiring an update from xbox live before the game is playable, that update only being offered on release day. I’d hate 2 see game companies having to resort to this, however game leaks do give an unfair advantage to those who sneak a copy, time spent in-game is invaluable when u take that online and compete against others.
