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 46: Adrenaline


This week we updated and added some enemies in Act 3, added various visual effects, made Neow changes, and worked on some performance improvements.

Act 3 Enemies
Several changes were made in Act 3. Some stronger jaw worms and a wriggly monster have been introduced into the enemy pool.

Reptomancer has been buffed and designated as an elite monster.
The elite encounter featuring 2 orb walkers have been removed from the elite pool and are the new guards for an Act 3 event.

Visual Effects?!

Yep. Various cards and an enemy attack have received some special effects to make them feel better to use! Some animations were added and improved for The Silent and Defect as well. More animations and effects will be coming!

Neow Updates!
We created Neow with the intent to foster creative deckbuilding. However, many have felt that the game was considerably harder without a blessing from Neow and the threshold to receive her blessing was too high (especially in higher Ascensions).

To compensate, we've added a fixed set of choices for those who don't reach the Act 1 boss (Neow's Lament or HP bonus).

Additionally, two new Colorless Card-based blessings were added as these cards weren't seeing much play as they only appeared in shops and certain events.

Community Fan Art
Such amazing art. I will try to get better, too! If you want to be featured, just mention @MegaCrit on Twitter!

Weekly Patch 45: Impatience

Hey again,

This week's focus was on refining upcoming content, prepping for mod support, various bug fixes, and a new option to disable particle effects for low performance machines.

Disable Particle Effects

We added a new option that removes particle effects from backgrounds and various effects.
This should improve performance for slower devices and decrease battery consumption for laptops.

Final Call for Translations
When we leave Early Access, outdated translations will need to be removed. If there are any outdated languages that you want to see in the game, support and instructions for translation is always available at our Discord channel.
