Hello, a friend and I were talking about Halo Reach the other day and I decided to join him for some games. He has an Xbox One and Reach is backwards compatible. However, I am still using the 360 (my job doesn’t allow me a lot of time for games and keeping up with them) and what we were not sure about was whether or not we would be able to join each other in matchmaking. Does it matter if you are using two different systems?
