they come out with the halo 3 O.D.S.T game
The maps are Assembly, Orbital, Sandbox, Citadel, Longshore and Heretic.
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.
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).

Mythic map pack mythic mature pack
Longshore is part of a map pack containing three maps that are not out yet. The mythic maps, Assembly, Sandbox and Orbital have come out recently but that was only one half. They are available for 800 Microsoft points on Xbox live. I have heard that longshore and the other two maps are supposed to come out Autumn this year.
Orbital, Assembly, Sandbox The newer version, the "Mythic Map Pack II," includes Heretic, Citadel, and Longshore
