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.
Yep.
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.
when ODST comes out
halo wars comes out march 3rd. halo ODST comes out sometime in fall. (in case any of you were wondering, halo 3 recon has had it's name changed to halo ODST.) halo wars comes with assembly, orbital, and sandbox while halo ODST comes with heretic, longshore, and citadel. YOU MUST BUY THE LIMITED EDITION!!!
when you bought ODST, it should have come with another disk; the Mythic mappack disk. plug in this disk and multeplayer will be yours! it comes with ALL maps, even legendary and mythic maps, and has forge and theatre and all that good stuff.
Halo 3: ODST will come out on 22/09/09 09/22/09
You must buy Halo 3: ODST and the game will come with two discs. One for campaign and the other for multiplayer games like matchmaking, custom games, and Forge. The multiplayer disc is the same thing as Halo 3 but upgraded to Halo 3 Mythic and you will automatically have all the mythic maps.
It comes with it, but if you have all the old map packs it may not be worth it.
Yes and no The achievements will be counted the same and so will the disks but if you have the ODST multiplayer disc (Halo 3 Mythic) and you join someone's campaighn on regular Halo 3 it won't work same thing if someone on HAlo 3 regular joins a map that comes with ODST for example SandBox.
you get the multiplayer beta with odst but not the whole game it the beta comes out may 3rd 2010 halo 3 odst included also xbox live gold
this fall
