play sonic in halo just download and the maps change
cant download halo 3 map pack, error message : premium is blocked
When on Halo 3 in Pre Game lobby you press start and chose Xbox Marketplace. From there you can download the maps and other Halo 3 content.
yes and no. You can play all the maps in the halo 3, but you have to download the rest.
You have to have Xbox live, and you download the maps.
How else would you get them.
Yes you can
no, you have to download the rest
all of them i believe
What you have to do is for the Xbox 360 you have to connect to Xbox Live then you have to get Microsoft points and download the maps but most of the maps are free.
