How do I download customs on Halo 3 on the XB1?

Games Other Halo

I’ve just downloaded my favorite game from all time on the Xbox One because I saved the disc. I had all the DLC maps, custom maps made and game modes. I’m really looking forward to playing strictly halo 3 since the MCC rotates the same 4 halo 3 maps any chance I get to play. A few questions though:

Will my custom games and maps be saved from the 360? Or will I have to find the same modes again online? (Like the file share or bungie.net)

If that’s the case how do I go about downloading my favorite custom game modes and maps? I’m really hoping to play ghostbusters, jenga, even trash compactor to bring back some memories.

Do your rankings and multiplayer progression transfer?

Do I need to pull out the old 360 and put my memory on the cloud? Hoping I don’t have to.

And any tips or advice would be greatly appreciated !

Go on to your Xbox 360 if you still have it, and save all of your customs maps and games types on to your cloud. Its a pain, but so far that’s the only way of doing it.

EDIT: Or if you have friends how have them, save after you play
