Where did the “Old Halos” forum go?
Where do people put their reach (and older) problems?
I guess more problems persist in newer games making it pointless to keep the old halo suport a thing with not many support questions being asked.
Classic Halo Games is the place for discussing the older Halo games, this forum (Halo Support -> Other) would be the place to ask support related questions. As most of the older games (Reach included) aren’t full supported or supported at all anymore, it could be a while before you get an answer to your question.
If you need a fast answer about Reach problems, you can publish your question on Halo Reach traditional forum. Many people are publishing their questions there.
