As you all know, there are commendations and challenges that you can do to get that extra XP. However, I don’t know how they work, or how I can complete them. Then for Spartan Ops, I thought that the first episode was already in the Halo 4 copy. Until I realized that you needed Gold, I was a bit disappointed. But anyway, does the commendation and challenges require Xbox Live Gold membership, or am I forgetting something? I have Silver membership by the way, so I can’t join the awesome multiplayer experience.
