Okay so I’ve had a bit of a rough time with Halo games in recent times but to top it all I’ve found today that my profile has been reset to rank 1, all my reqs are gone and at the end of a multiplayer game the darn thing cannot retrieve data! Please please can we have a Halo game that just works!

And my game worked fine last night! I love halo but if this is how it’s gonna be ill go play me some destiny. At least that’s working. Bungies still at the top of their game in my opinion.
