Yes.
you have to have odst and it comes with an halo 3 mythic multiplayer disk and you get it with that
No, the Halo 3 game disk has both the campaign and multiplayer mode on it. What might seen confusing is in Halo: ODST, the game comes with two disks. One disk is for the Halo: ODST game and the second disk is for the Halo 3 multiplayer with all the latest map packs on it such as Mythic
Getting the katana sword would mean you would have to unlock every achievement in the game. So you would need both the regular Halo 3 disk for the Campaign achievements and the mythic disk for the online and multiplayer achievements.
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.
No. You either need to purchase it from the marketplace, or you can get the mythic disk when you buy Halo 3: ODST.
Yes that's the purpose of the multiplayer disk. the odst disk has online multiplayer to.(4 player co-op campaine and fire fight)
well if you have the mythic disk you just select a ramp but if you dont have the mythic disc your screwed on that one I think
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.
The HALO REACH multiplayer beta is coming in May. When it does come out put your Halo 3 ODST game disk in and in should be on the Disk menu.
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).
The ODST disk look for more help at bungie.net
If you mean the Multiplayer disk that came with ODST then yes, but if you mean the ODST campaign disk then no.
