I was absentmindedly reading Blizzard's interview with the Ghost team when I saw something that brought me into the present moment.
BI: What is the game's multiplayer like? How long do you expect multiplayer games to last?
GT: The plans for multiplayer are still evolving and a lot still needs to be kept under wraps, but we can say this - the MP gameplay will support a cooperative aspect as well as combative - and will add some great content over and above the single-player missions.
What's this, now? Last I'd heard, they were still discussing it. Now we've moved up to for-sure multiplayer, co-operative and otherwise? Happy day!
