Hi all,

I say you can play multiplayer campaigns like a hotseat and sending them via a program that works for LAN/Hamachi.I say it's a 3rd party program and it's not an official CA program!!! But I have tested it and works.
In this video you see a description and there are the downlading links that they are in www.twcenter.net. In any case just PM me!!!
