I cannot defeat the Invasion campaign. The Orange players are way too strong. If I try to build up my armies, they come and wipe me out. If I try to rush through, they wipe me out. The best I've been able to do is capture two towns, but I lost so many troops in the process that the Orange player easily wiped me out. I don't have any patches (unfortunately I have a foreign version of the game and don't know enough about eastern European languages to know which patch to install). I've consulted several walkthroughs to no avail. I just cannot seem to build up enough strength quickly enough to defeat this campaign. Help!!
