When you have downloaded them. They will automatically work.
they come out with the halo 3 O.D.S.T game
go on machmaking
yes they do. you can probly get it downloaded online, but maybe a store still sells it.
well that is happening so try download it again
They have not downloaded the proper map pack, and will need to, to play that map.
go to custom games and look at the maps, it should show a star next to any new map u downloaded
it depends if you have halo Reach, 3 or ODST. but if you have Reach you should just have to select it from your hard drive storage and play it. To get the gamemode it usually comes with the map.
I would assume you install it.
No, it must be downloaded to your HDD from the Xbox Live Marketplace.
that happend to me but when i switched the xbox off once or twice then they were all there --------------------------------------------------------------------------------------------------------------
