You have to have Xbox live, and you download the maps.
You can't. The Mythic Maps our only playable on Halo 3, not Halo Wars.
play sonic in halo just download and the maps change
Yes, halo 3 mythic is the exact same thing as halo 3 just doesn't have the campaign, also Halo 3 mythic has the new mythic maps included. Online will not change during any gameplay.
Sandbox, Orbital, Assembly, Longshore, Heretic, and Citadel are the maps released in the Mythic Map Pack, and are called the "Mythic Maps" for short.
They are skulls. idiot.
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.
All of the maps, including The Mythic map pack 1 and 2, come on the Halo 3: Mythic disk that is included with ODST. If you don't want to buy ODST, I believe that the full Mythic maps are available on Xbox Live marketplace.
No, they cost 1200 Microsoft points.
yes no maybe i don't know
You can't, you need Xbox Live
The mythic maps are officially coming out on April 9th, read the bungie posts on bungie.net.
Last time I checked there was a specific mythic map only game type.
