Yes that's the purpose of the multiplayer disk. the odst disk has online multiplayer to.(4 player co-op campaine and fire fight)
If you mean the Multiplayer disk that came with ODST then yes, but if you mean the ODST campaign disk then no.
The ODST disk look for more help at bungie.net
Yes.
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
As far as I know, you can't because their isn't any online Option in Halo 3 ODST; Campaign Disk, BUT if you were to use the Multiplayer disk, you can get online/matchmaking, and play online, and get anywhere between 1 and 3 exp for games.
you have to have odst and it comes with an halo 3 mythic multiplayer disk and you get it with that
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.
On the second disk, the multiplayer disk.
no
No you don't , Halo :ODST is a stand alone game that has 2 disks : 1- ODST story mood and a multiplayer mood called firefight 2-A disk that has all the Halo 3 multiplayer maps that you can play WITHOUT the need to have the original Halo 3
you need halo 3 ODST to access the halo reach multiplayer beta
You get the Halo 3 ODST campaign and Halo 3 multiplayer. Nothing else.
