Yeah, looks like it's confirmed that there is NO multiplayer at all:

"...but when asked we were told that the decision had been made because there was no desire to add a multiplayer mode or any other girth that would distract the team from making the best version of the single player campaign possible."

That's baaad. Single player have to be awesome now.
