Bungie and Microsoft have announced that as of 2 a.m. this Tuesday, March 25th 2008, the previously released 800 M$ point Heroic Map Pack will now be free to download on Xbox Live Marketplace. If you own Halo 3 and haven’t already paid for these maps then you should definitely grab them. They’re free, ’nuff said. Bungie will also be releasing their new Legendary Map Pack soon for the same initial 800 M$ points. Look for that to be free sometime this fall.
