Recently it has been confirmed that there will be multiplayer in the DWCM. Right now there isn't much in it due to the enourmous 1.5/1.6 update. Confirmed multiplayer related things are:
-Official Doctor Who Client Mod "play" server
-Official Doctor Who Client Mod "build" server
-LAN -(Local Area Network) Which also means that you will be able to play with your friends while on the same WIFI connection.
Well that is all we know for now folks. Enjoy your jelly babies in a tub of ice-cream!
