About this game

🏰 Legacy of Kings: Plague Era – Can you survive the Great Sickness? 🛡️
The once-mighty empire has fallen. A devastating pandemic has swept through the realm, leaving a toxic green contagion in its wake. This is no longer just a game of building—it is a battle against the Black Death.

In this idle tycoon, you are the last hope. Rebuild a kingdom from the ruins of a dark apocalypse. Clear the infestation from your lands, manage resources amidst the sickness, and restore life to a world choked by disease. Whether online or offline, your mission to cure the land continues.

💀 FIGHT THE EPIDEMIC, REBUILD THE REALM
The world map is hidden beneath a lethal plague haze. As a leader, you must venture into the green mist to reclaim your territory.

Purify the Land: Accept vital quests to clear the infection from tiles surrounding your cities. Watch the toxic clouds lift as you push back the contagion.

A Gritty Medieval World: Experience a haunting atmosphere filled with boarded-up houses, lonely graves, and the shadows of rats and crows circling ruined castles.

From Ruin to Royalty: Take over a dilapidated, abandoned castle and transform it into a fortified sanctuary against the outbreak.

🔹 WHY YOU’LL LOVE LEGACY OF KINGS
Strategic Survival: Rule over a medieval dominion ravaged by the plague and build a flourishing empire once more.

Automated Restoration: Your production thrives under your command—automate supply chains to fuel the fight against the infestation.

Explore the Wasteland: The vast world map is full of secrets—discover hidden splendors buried under years of sickness.

Idle Progress: Your influence expands even when you’re offline, making it the perfect strategy for survivors on the go.

No Pressure, Just Strategy: Delve into a realm where the only pressure is your own strategy to outsmart the Black Death.

Legacy of Kings isn't just about rebuilding—it's about surviving the plague. Enhance your strategy, manage your resources with finesse, and heal the world before the contagion takes it all.

Will you rise from the ashes, or fall to the infection?

No forced ads. This is a pretty fun building and exploration idle game. The main draw back is that your income does not keep pace with escalating exploration costs, so now at level 23 I can only explore a few squares at a time, so I'll probably get tired if it soon. Otherwise it'd be 5 stars. Similarly, treasure does not scale with level, so now it costs many times the value of the treasure to actually get to it. Did not tire of it, glad I didn't, upgrades inproved my exploration rate.

Great game and great execution of the clicker concept. There are a few gripes, like having a quest dialogue box always pop up above the capital, without being able to toggle it off. Or when I can toggle it off, it somehow sometimes double clicks the tile beneath it. But otherwise, really great implementation of the clicker concept!

Well, generally quite alright, I guess. Unfortunately, games' main feature is becoming the main pain really fast & I'm talking about exploration. Not only is it extremely costly, and it requires you to click one tile 15 times in a row, but also, the UI is so... weird that you will start planting trees around the place you want to explore, completely due to missclicks. Fun for a while, dreadful on a long run.

Hi! Thank you for taking the time to share such detailed feedback. We’re glad you found some fun in the game, but we’re sorry the exploration feature and UI design made the experience frustrating over time. Suggestions from our community are important to us and we’ll be looking into improvements so exploration feels more enjoyable in the long run.
