The tips were very helpful!
But I have a question: if I want to upgrade Wolfshtein, Frida, and Kujin in the new version, do I only need to complete the missions in which they are involved? Do I need to complete the entire campaign? Because I tried with Wolfshtein, but he still didn't go into battle as strong as I upgraded him... What did I do wrong...?
Version 3.1, and also, I have this bug throughout the entire campaign: creatures don't improve either in the Fortress or in the Castle... Is this a glitch, or is it happening to everyone?
