Halo CEA Multiplayer question.

I’ve heard from several friends and other various sources that if you have Halo: Reach installed to your hard drive you can play the original Reach maps from the CEA disc. Essentially making it like the Halo 3 ODST disc.

Is this true? Any help would be appreciated.

Yes, you can install reach and gain access to those maps as well as the 7 new ones all on that one anniversary disk.

Ok. Great. Thank you very much.
