yes and no. You can play all the maps in the halo 3, but you have to download the rest.
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.
Yep i got them all, if you buy Halo 3 ODST you get them all including the other mythic maps
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.
halo 3 ODST will probably come with a second disc with all the Halo 3 Online maps on it (all 21) plus 3 more. will be halo 3 format.
haw to make mode maps in halo 3
The Halo Odst Disk 2 comes with all maps (Plus 3 extra), and the ordinary halo 3 disk comes with no added map packs, so you don't have another 12 maps.
You can't. The Mythic Maps our only playable on Halo 3, not Halo Wars.
you need all of em...
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.
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.
no, you have to download the rest
