It's a multiplayer map... they were talking about multiplayer. He mentioned Control, and then asked if it would be available for all game modes. Meaning the multiplayer game modes/gametypes. They didn't say a single thing in that video about single player/co-op. Everything he said about humanity taking it back and using it as a staging area was just the backstory for the map. Bungie always tries to create maps that have a backstory... a reason as to why you're there.
