the multiplayer content / infinity content is on disk 2
It is not on a disc! It is on the sheet that says Halo Reach, But you will need Xbox Live.
Xbox Live
You have to put in the Mythic disc, then its the same way as Halo 3.
yes, but its only multiplayer as in against each other
Yes, Halo 4 comes with two discs. It has the main disc, which has the campaign and spartan ops modes, and the secondary disc which you put in the Xbox and download. Then you can take it out and play multiplayer (War Games) on the first disc again.
Maybe your disc was a preowned and the previous owner scratched or something
By getting halo 3 odst ( two discs ) first disc halo 3 odst campaign and 2nd disc halo 3 mythic comes with all the halo 3 maps.
Like i tried Halo 3 but a message came up saying Halo needs the disc but will Left 4 Dead 2 be good to go? I don't want my Xbox working hard on spinning the disc if it doesn't have to, seeing that this is my 5th Xbox... : /
Either the game is corrupted or the disc is scratched up
halo 4 is coming out in november 2 2012.
