Once Upon A Kingdom
Steam
Step into a storybook world where you’re the King. In Once Upon A Kingdom, you'll lead unique civilizations through the ruins of forgotten worlds in a strategic blend of city-building, card-based gameplay, and light tower defense. Every decision is drawn from your deck — from vital structures and clever combos to last-minute defenses against relentless threats. Each game is a story of your own making, each card a choice that reshapes your reign.
Build wisely, defend boldly, and unearth the forgotten forces that shaped your kingdom’s fate.
Build your city by drawing and playing cards — no two sessions play the same. Manage your economy, infrastructure, and upgrades through strategic hands and carefully timed combos.

Enemies will come for your kingdom, and how you build will decide your fate. As you expand into new lands, each unlocked tile brings surprises, risks, and rewards. Defense zones add a strategic layer that challenges how you grow, adapt, and prepare. Place the right buildings, time your draws, and protect your kingdom.

Deck randomness meets long-term progression. Master card synergies, upgrade your deck, and chart your own path shaped by your choices. Will you expand early, defend hard, or wait for the perfect card?
Myths aren’t just stories here — they’re your blueprint for rewriting history. Step into legendary chapters drawn from ancient legends and conspiracy-laced tales. Rebuild fallen civilizations across distinct campaigns, from Pharaoh Xehtor’s pyramids, to the aftermath of the Great Flood, to secret settlements on the Moon. Each chapter is a myth reimagined, placing you at the center of a kingdom lost to time… until now.
