I did actually start work on a SP German campaign for CoD2 though stopped because I didn't have enough reference pictures to redesign Fornebu Airfield (in Norway). I got the German soldiers to work as friendly ones and Allied as the enemy but I am just too fussy when it comes to buildings, if someone helped me make the buildings then it could really take off.
Here is an example of my shocking construction skills:


I was going to do the campaign from the invasion of Norway to fighting in Holland then North Africa. If anyone volunteers to help me recreate a Norwegian Airfield then I would gladly do it.

What surprised me was that in CoD2 they already have the random name and rank generator for the German troops, and when you make the Germans friendly troops they respond like the Allied soldiers BUT IN GERMAN! It looks as though they expected someone to make a German campaign because they have made it easy to do so.


So yeah, if anyone is interested in helping me, let me know, I am perfectly happy to help anyone who is new to the editor learn (though in a week I am going to Europe for 21 days so I may be slow to reply).
