The Xbox 360 version of Halo 4 has been leaked online, and Microsoft is not happy (duh). The leak is definitely real, and I’m sure that the ones that leaked it will be caught and reamed badly. Not going to be a good holiday season for those that did the leak.
For those with modded Xboxes and are wanting to give this a try, I can suspect that Microsoft will be going through some very tough and frequent banning missions very soon. Is it worth it? Personally, I never really cared much for the Halo franchise, but even if I were – I don’t care much for the pirate scene. Modding, sure. The original Xbox was a huge modding platform that gave birth to the XBMC (Xbox Media Center), which probably contributed a lot to the 360 media features.
According to the publisher, Halo 4‘s second disc "contains data that will need to be installed on an Xbox 360 hard drive or compatible flash storage device with at least 8GB of available memory in order to access ‘Halo 4‘s’ extensive suite of multiplayer features." Microsoft has employed a similar system for first-party games like Forza Motorsport 4.
