if you have xbox live gold membership and a controller and an xbox36o then yes, yes you can
yes you can be a arbiter in only campaign multiplayer
you dont ever play as a scarab in Halo 3...you play as a scarab in Halo wars.
yes everything except multiplayer
You get the Halo 3 ODST campaign and Halo 3 multiplayer. Nothing else.
well may 3 you could have but its over now to play the beta get the halo reach on September 14
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
yes of course they do
Yes you can play both Halo: CE and Halo 2 multiplayer on PC.
If you install it onto your harddrive and insert the original halo 3 disk you can access the three extra maps and the matchmaking features.
yes only multiplayer has the new map packs but you can get them in the DLC
you can get all of the skulls on multiplayer. =)
If you mean the Multiplayer disk that came with ODST then yes, but if you mean the ODST campaign disk then no.
