Just "Armored Princess" with few new quests and some artifacts.
"New Campaigns" they said. Just unfair fights with bosses from Armored Princess. Not sure why this should be fun to have 500-1000 leadership (on easy) and try to fight boss 2400hp, damaging like 80-200 in first round. After it - mass damage every round. So you win, go re-buy your troops and again the same.
On higher difficulties it's just almost the same but boss get 5100hp and you have less leadership.

Strange solution. So 4 campaigns: original AR, Arena, Arena "v2", and extended AR.
Worth to buy if you do not own AR yet. That's why negative review.
