A free update for Kingdom: Two Crowns offers experienced players a new challenge, as well as some QoL changes and Bug fixes.

The Challenge Islands update is described as representing "the greatest challenge ever seen for hardened veteran monarchs. Can you survive long enough to claim the Gold Crown? ... There are three different Challenge Islands to begin with, each tailored for the solitary monarch as there's no co-op to help lighten the burden of the difficult challenges ahead. "

The Islands are:

DIRE ISLAND: With the new Dire Wolf mount as your aid, protect its pup at all costs. No crown, no monarch. No pup, no monarch! Now build the boat and try to escape as you run to as many islands as possible before the inevitable.

SKULL ISLAND: Time is running out and you must destroy the Greed Lairs. That's right, "Lairs" as in PLURAL! With a Greed Lair on each side and several Greed Portals in between, this challenge is fit for only the gods that walk amongst Monarchs. And don't forget about the volcano that is waiting to explode!

PLAGUE ISLAND: This land has been overrun and on the brink of succumbing to the Greed... FOREVER! And now a fearsome pandemic is transforming citizens into Greed. The only thing you can do is try to survive as long as possible until your Kingdom is nothing but Greed.

It is out now for Switch, Xbox One and PC players, PlayStation 4 players will need to wait a little bit longer. Additionally, two new achievements have been added for Xbox One, two new trophies for PlayStation 4, and two new achievements for Steam.
