Greetings, noble knights.
Steam Next Fest starts on October 19, and the updated Zodiac Legion demo is already playable. Here is a 30-minute Let's Play covering the new campaign and combat mechanics: research, construction, roster management, the world map, and tactical combat (support, traps, movement checks).
If you are already familiar with some parts of the game, you can use the chapters on YouTube to jump straight to the part that interests you.

May the stars watch over you!
