ya you have to download a program onto your Xbox 360 and it lets you play as any thing you want but they are only character skins and the covenant will still attack you
you cant unless you make a mod or somthing
you cant play as a grunt
yes, unless you want to play halo 3 mythic which comes with ODST
Yes and no. You do not need Halo 3 to play ODST. And you do not need to have played Halo 3 to play ODST. It is an expansion of the Halo storyline. I happens concurrently. No its not this is not an expansion of the story this is just another part of the story.... so basically whats happening in the game halo 3 is happening at the same time as whats happening in halo 3 odst.... They are just two different battle fields. ODST are not Spartans either they are like elite marines Halo 3 odst is between halo 2 and halo 3.
No
Yes, you can play firefight in Halo 3 ODST without Xbox live.
If you mean the Multiplayer disk that came with ODST then yes, but if you mean the ODST campaign disk then no.
There is no way to get it without the Halo 3: ODST Campaign disk.
