Will there be co-op, online play, multiplayer?

If the hero is nameless as in ds / bb, then it is possible (if lorno introduce "phantoms" of opponents). Otherwise, it will be harmful. In terms of gameplay, it's hard to say, the combat in the first one was good and in some cases the co-op would have gone to the detriment. Of course there is the last boss, which is a little stuffy, but still the balance of the game was for one. I think that the developers will make a deuce single.
