You must go to the XBOX LIVE Marketplace for Halo 3 and download the maps and map packs. But some will cost you with Microsoft points. Or you could buy Halo 3 Odst which comes with a disc that is specific for online, custom games, and forge with ALL the Maps.
you cant >:(
If you install it onto your harddrive and insert the original halo 3 disk you can access the three extra maps and the matchmaking features.
haw to make mode maps in halo 3
By getting halo 3 odst ( two discs ) first disc halo 3 odst campaign and 2nd disc halo 3 mythic comes with all the halo 3 maps.
Yes
You can't. The Mythic Maps our only playable on Halo 3, not Halo Wars.
When on Halo 3 in Pre Game lobby you press start and chose Xbox Marketplace. From there you can download the maps and other Halo 3 content.
i do belive there will be a forge to make maps like Halo 3 did.
play sonic in halo just download and the maps change
yes and no. You can play all the maps in the halo 3, but you have to download the rest.
If by "halo 3 maps" you mean the Halo 3 Heroic, Legendary, Mythic and Cold Storage maps, then yes. However to play campaign levels, you must actually advance in the game to get to them.
on bungie, when you find the map you want, que it for download and when you next log onto halo 3 xbox live on your 360 it will automatically download.
