So the multiplayer aspect is shutting down on the xbox 360 Halos but does that include forge? Ive made forge maps with friends and weve had great memories and it would be sad to see them get deleted or locked.
I think customs will still be up. I think your maps are fine…
I would guess that Forge will still work. However, I would guess that the File Share system will shut down.

There is a handy chart that shows what will be affected in which game.
Forge is still operational for all legacy titles.
