About Once Upon a Galaxy

Once Upon a Galaxy - about the game
Captain a crew drawn from myth and fairytale characters in this fast-paced, free-to-play card battler set across a vast galaxy. Select a unique Captain like Dorothy, Dragonmother, Indiana Clones, or Geppetto at the start of each game, then recruit allies, cast spells, and position cards each round for auto-battles against opponents. Upgrade your board and crew with synergies from factions like treasure-focused Dragons, spell-boosting Mages, or summoning Toys, drawing from a shared pool plus your Captain's elite collectibles. Async multiplayer pits your runs against real player boards whenever you choose, with cross-platform progress syncing from PC to mobile. Monthly Captain releases keep strategies fresh in casual indie play. Fans of strategic card games and auto-battlers find endless replay through smart synergies and no-pressure matchmaking.

Once Upon a Galaxy is a fast-paced, free-to-play card battler of cosmic proportions. Captain a crew of characters from myth and fairytale lore into battle across a spectacular galaxy in search of allies, spells, and treasures to ensure your ultimate victory!

Begin each game by selecting a Captain with its own unique effect.

Will you choose Dorothy to help complete her friends’ quests? Or Dragonmother to discover what hatches from her Mysterious Egg? Play as Indiana Clones to "clone" your best three treasures, or lead a troupe of toys as Geppetto!

More captains are released each month, so there’s always something new to try!

Galaxy features an eclectic cast to help you on your journey. Recruit characters and cast spells each round to prepare for your next challenge. Carefully position your cards while planning your turn—then enjoy their auto-battle against other captains and crews!

Upgrade your crew throughout the game. Character-copies give bonuses and discover powerful treasures. Enhance your board directly to keep buffs as you replace characters. The most powerful cards appear later in the game—find a Legendary crew to help make you the last captain standing!

You can capably lead any odd character, but your most powerful crews will come from smartly-selected synergies. Combine treasure effects with characters’ abilities for powerful outcomes. Leverage powerful character factions, each with their own focus, such as treasure-loving Dragons, spell-enhanced Mages, or Toys which summon additional characters during the fight!

In addition to the common pool of cards you encounter each game, each captain commands its own list of collectible elite characters to customize your plans. Select 12 cards before the game—they’ll be mixed into your card pool to potentially draw!

No timers, no pressure. Galaxy's matchmaking and async-multiplayer mean you can battle fun-but-challenging opponents whenever you want. Face real boards from other human players’ earlier games. Your finished run will join the opponent pool for others to challenge. It's fast, strategic, and endlessly fun!

When you're ready to crank up the intensity, you can play with friends in 6-player live lobbies... warning: live lobbies are the ultimate competitive experience!

While our Steam build is great for the desktop experience, Galaxy is also available on your phone or tablet! With a cross-platform account, you can sync your progress no matter which device you use and so can explore Galaxy on-the-go!

Once Upon a Galaxy is created by Million Dreams Games, an indie studio boasting a talented team. Our leads have worked on iconic games like Magic: The Gathering, Hearthstone, and Runeterra. We’re diehard fans of the card and auto-battler genres.

We believe in building a fully-functional free-to-play experience. We partner with wonderful artists to bring our vision to life (no AI artwork is used in Galaxy).

If you love our game too (we think you will!) and want to support us, you can boost your collection rewards or style your favorite cards with alternate-art skins. A monthly Galaxy Pass offers both!

Give Galaxy a try and experience the thrill of this groundbreaking card battler.
