Change your region from the country you have set it to USA or UK. Restart your console and halo 3 should now work!

Does not work for me when I am going to play the campaign, it just freezes at the loading screen 
Have you set your region to United states? It should do the trick 
No… How in anyway is that a good idea? If you’re not in the USA, this is a BAD IDEA. Stay in your region. For latency sake.

If you want to play h3 and can’t in your region i suggest you do as i said.
It’s better than not playing Halo 3 at all!
Or you could change it to a nearby country that works.
Thanks for the solution, I’ll try it now!

I don’t know if you can change it to nearby countries. I only know that United States works.

I live in Sweden, and the UK works for me!
Ok good to know!
Changing your region works. Changed mine to UK and I live in Sweden.
Thanks for the help! Much appreciated!
No problem. Glad i could help.
This is fantastic! I think this should be stickied since it’s a solution to a pretty severe problem. It should be enough until they can figure out what’s wrong.
