Kingdom Two Crownsis a city building game with an interesting twist thatintegrates tower defense elements. The core of the gameplay is improving your kingdom and expanding as far as you can, but defending said kingdom and eradicating the encroaching greed is one of your main objectives.
As you progress through the game, you’ll need to upgrade your town center to recruit knights that can attack greed’s portals. However, after a certain point, you won’t be able to upgrade it any more without obtaining stone. Stone Technology is the next step to uniting the lands under one ruler.
How to Unlock Stone Upgrades in Kingdom Two Crowns
Many buildings don’t let players upgrade them any further until they unlock stone technology. For example, walls and archer towers cannot be upgraded to tier three, and the town center doesn’t go beyond Tier 4. To get these upgrades, players need to obtain stone,an important resourcethat can be found on the second island.
To get it, players need to travel to the second island, find the stone mine located there, and activate it. This mine is an obelisk-like stone structure which needs 10 coins to be activated. Once players activate the mine, they’ll get unlock stone technology and get access to the following features that weren’t available before:
If you leave the second island without activating the stone mine, you’ll need to return in order to gain access to stone technology. You cannot directly advance to copper from islands that are further ahead.
How to Get to the Second Island
To reach the second island, players need tofind and repair a ship. There will be a ship wreck on the starting island, which will only take 10 coins. If you’re on the first island, you don’t need to spend any money on ship parts, the game will provide them alongside the ship’s hull. Wait for the workers to finish construction and pay two more coins to get the ship into the water.
Once in the water, workers will come and push the boat to shore, where players can pay ten more coins to leave on an aquatic adventure to discover more islands. After the cutscene finishes playing, click any of the arrow keys to bring up the map and select the second island as your destination. The ship will crash on the island, leaving you free to explore and build. If you want to go back to the first island or go to a new one, you just need to rebuild the ship and repeat the process.
