muythic map pack. that comes with HALO 3: ODST
they come out with the halo 3 O.D.S.T game
Yes, the ODST Mythic Disc does include every DLC map; Heroic, Legendary, and Mythic Map Packs, including all original Halo 3 maps and the newest maps (Citadel, Heretic, and Longshore).
when ODST comes out
yes only multiplayer has the new map packs but you can get them in the DLC
There are some in Halo 3 ODST.One on Heretic, one on Longshore and one on Citadel.These maps are the new mythic map pack.
The maps are Assembly, Orbital, Sandbox, Citadel, Longshore and Heretic.
Sandbox, Orbital, Assembly, Longshore, Heretic, and Citadel are the maps released in the Mythic Map Pack, and are called the "Mythic Maps" for short.
It will have a different campaign mode and all of the halo 3 maps but it will also come with both halfs of the Mythic Map Pack (Assembly, Orbital, Sandbox, Citadel, Heretic, Longshore).
It's behind a ventalation pipe near the main base on the side of the map with the wall, as apose to the side with all ocean
That is dabatable, however most people would say the DLC map Sandbox, especially if you manage to stop the guardians from killing players.
