Halo 3 ODST?????????????????

[taylorb2014]

im confused, the sites tell me that halo 3 odst( coming out next week) comes with two disks one for campaign and one for "the maps without starting halo 3 up" what disk has the new firefight mode and what do they mean by a disk for the maps without starting halo 3 up

 

[wizardsfan]

The first disc is the new campaign only.
The second disc is multiplayer with all halo 3 map packs included, mythic, legendary, all the ones you have to buy and dont have to buy.
Comes out 9/22/09
Disc 2 has firefight mode because its multiplayer.
