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
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 you can play both Halo: CE and Halo 2 multiplayer on PC.
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.
