Alright, time to say something Bungie announced from the get go. When you buy Halo 3:ODST, you are getting two discs. Disc One has all of ODST's features, meaning this is what you put in to play the campaign and Firefight mode. Disc Two is the complete collection of the Halo 3 Multi-player. This disc will contain all of the maps, both DLC and normal along with the three new map packs. You will be able to delete the ones you have on your HD to free up space if you wish, as the Multi-player will only run off of this disc. However, this does not mean you can download those maps to your HD. Bungie has made it clear that you cannot, but it is there for those who need the extra space. Still if you want to play Halo 3 campaign, you'll need your original disc. I am not sure how the other modes are affected by this, and will not know until I get my hands on it. There you go, I hope you have you questions and worries answered. [/end transmission]
