You have to take command of the thirty best soldiers and lead them along not the easiest, but the most worthy path!
- a lot of unique equipment
- powerful squad skills
- extensive skill tree
- soldiers training
I have no idea how 20ish soldiers can survive against so many enemies when just one skirmish can nearly wipe out half your troops. And gold and silver..it's basically just a paywall to upgrade to win. Not worth it. Maybe an easier few levels to get gold and or silver first.
