Early Access Game

Get instant access and start playing; get involved with this game as it develops.

What the developers have to say:

Why Early Access?

TL;DR: Slay the Spire currently has loads of content and lots of polish. We want to use Early Access to make it even better. We will be releasing updates every two weeks with new content, fixes, and incorporating feedback. To thank our supporters, Slay the Spire will be discounted during EA!


We believe that games that make best use of Early Access are the ones that actively engage with their communities. Frequent updates based on feedback and community input is exactly what we want to provide. By putting Slay the Spire into the hands of the players, we can make an already fun experience even better.”

Approximately how long will this game be in Early Access?

“The game will be in Early Access for around 4-8 months. We have been working on Slay the Spire for over 2 years, and believe that this is the amount of time needed to finish up the game with all of the content and polish that we want.”

How is the full version planned to differ from the Early Access version?

“The full version will have lots of additional and improved content, including a new character with an entirely new card set. Leaderboards, daily runs, and social features will be incorporated as the community grows. We will be directly looking to the community to determine how and when new features and content gets added.”

What is the current state of the Early Access version?

“Currently there are:

  • Two core characters that each have their own unique set of cards.
  • ~200 cards, most with unique upgrades.
  • 50+ unique combat encounters.
  • 9 different bosses
  • 100+ different items to be found.

At the current stage, Slay the Spire already has tons of content to explore and great replayability. Right now, fully beating the game takes an average of about 15-30 hours. The main focus of Early Access will be harnessing community feedback to improve the game even further.”

Will the game be priced differently during and after Early Access?

“Yes. Early Access supporters will receive a lower price. We plan to raise the price when the full game is released.”

How are you planning on involving the Community in your development process?

“Working with the community is the heart of why Slay the Spire is going Early Access. Throughout the Early Access process we will be working with the community to improve the game.

Community members will have the chance to have their own card ideas implemented into Slay the Spire! Details on this will be coming soon.

Nobody is better at discovering broken strategies than a thriving community. Through listening to your feedback, balance will be continually refined.

All ideas and feedback will be welcomed and seriously looked at. Maybe your sweet card idea will even make it into the game!

For the last 2 years we have been tirelessly fixing bugs with a team of internal testers. However, with so many permutations of cards and new content coming in, there is bound to be more issues. We believe that having a bug free experience is key in immersing yourself into the game.

With so many cards (and text) there is a lot to translate. We want Slay the Spire to be seen by as many people around the world as possible, and we cannot do it without community support. Players that understand the game on a deep and technical level always create better translations than outsourcing to non-players. Stay tuned for more.”

Weekly Patch 48: Creative AI

Happy Halloween (yesterday)!

This week we mainly worked on the final content which is now being tested in the beta branch! However, various fixes and improvements while working on this has carried over as well.

Final Content
It's currently being tested in the beta branch. It's on track to make it into the main branch this month (November)!

Beta Art!
When implementing cards throughout the development of Slay the Spire we drew and received a lot of placeholder art before our talented artists gave us finalized artwork. We've decided to share this artwork in the game but there's a problem: Not all of our cards have placeholder art.

We need your help to fill in the missing art or the beta art feature may not make it into the full release :(.

To help us resolve this crisis, please take a look at this secret document which indicate what cards are missing beta art.

For contributions, we need a 500 x 380 PNG image that match a card template based on the card's type (templates below). Anything outside of the template will be removed. Note: Status and Curse cards utilize the Skill template.

Attack template

Skill/Status/Curse template

Power template

Submission Guidelines
Though we encourage any kind of art, please keep in mind that suggestions may be rejected for the following reasons:

  • Suggestive or offensive content.
  • Too little effort.
  • Too much effort, you're making us look bad.
  • Too many submissions from a single person (let other people have fun, too!)
  • There's already art for that card, we can only have one slot. Sorry :(.
  • The art is not related to the card at all.
  • It's too late (noooo).

Once your submission is ready, either post the image and tag us @Developers at our Discord server, or email us at support@megacrit.com. We cannot accept submissions through Twitter as the image will be severely compressed.

About This Game

We fused card games and roguelikes together to make the best single player deckbuilder we could. Craft a unique deck, encounter bizarre creatures, discover relics of immense power, and Slay the Spire!

  • Three core characters that each have their own unique set of cards. (With more planned)
  • 200+ fully implemented cards.
  • 50+ unique combat encounters.
  • 100+ different items to be found.
  • Procedurally generated levels.
  • Tons of unlockables.

Dynamic Deck Building

Choose your cards wisely! Discover hundreds of cards to add to your deck with each attempt at climbing the Spire. Select cards that work together to efficiently dispatch foes and reach the top.

An Everchanging Spire

Whenever you embark on a journey up the Spire, the layout differs each time. Choose a risky or safe path, face different enemies, choose different cards, discover different relics, and even fight different bosses!

Powerful Relics to Discover

Powerful items known as relics can be found throughout the Spire. The effects of these relics can greatly enhance your deck through powerful interactions. But beware, obtaining a relic may cost you more than just gold...
