Valentin, I am Playing Nazi basterds, Eastern campaign, 1941. Re Upgrading units - the game guide says that cities with gold trim are better for upgrading. I am trying to upgrade 76mm artillery at Koenigsberg to (anything good) but I get the error message, you need to be at a big city to upgrade. It has the appearance of all the big cities on the map; is there a more reliable way for me to know which cities can upgrade units or not?
It is a captured unit, is this a factor?
Question 2, core units: Why are all captured units core units, and how come the core unit system is so unworkable and non-instinctive?
Question 3, campaigns: I completed the first campaign of only 2 maps, is that correct or did I do something wrong ... can we get more info about campaigns please!
Thanks for your time and ongoing work my friend.
