Bungie.net user Chevmeister, on his own volition, clearned out each of the maps from the Heroic Map Pack and made those files available for download in his File Share. We've taken his files and placed them in
Bungie Favorites where they can be downloaded directly in-game or if you're logged in to Bungie.net, you can download them to your Xbox 360 the next time you boot up Halo 3 by clicking "Download to Halo 3."
NOTE: If you haven't
purchased the Halo 3 Heroic Map Pack, trying to download the free "empty" maps (or any other Forge creations) from Favorites will not result in you magically
acquiring the maps.
