All I know is the Wii U version has co-op.
What is this talk of co-op? I haven't been keeping up to date with this topicIs it just solving the world's problems together while saving your sister or is it a whole new adventure?
Another person picks up a wii-remote and when Maxwell spawns a object the other person can become it and control it around.
Is it possible to use a character downloaded from workshop to be used as an avatar?
I don't think so.
Yesterday I bought the game,I uploaded to workshophttp://steamcommunity.com/sharedfiles/filedetails/?id=122903383&searchtext=
