Slay the Spire 2 vs Slay the Spire: What's Actually Different?

Slay the Spire set the standard for modern roguelike deckbuilders. Slay the Spire 2 has big shoes to fill, introducing co-op, new characters and a revised ascending system whilst keeping the same core gameplay as the first. This guide will help you understand what has stayed the same, what is different and how the first iteration still wins out. It will also show you how to get the best deal on both games. Please note that this guide is accurate for mid-November 2026 and may change as Mega Crit adds more content to the sequel.

What Both Games Share

Both games are roguelike deck builders. You pick a character and work your way up the randomly-generated spire, collecting cards to build your deck. Each act consists of a number of branching paths containing combat, events, campfires to rest at and shops to buy cards (and remove them from your deck). Combat is turn based and you have limited energy to use. Enemies tell you what they’re going to do next. If you lose you’ll have to restart. If you’ve played before then many of your instincts will already be there. Things like reducing your deck size, not taking cards that aren’t great and knowing what your enemies are going to do will all come naturally in the sequel.

What Is New in Slay the Spire 2

Cooperative play for up to four players

The biggest addition here is the online co-op element. Players each choose their own character, with their own separate HP, deck and resources. You can also heal, protect, buff and debuff your allies. There are some cards you can only get in multiplayer mode. To balance the party enemies have more HP and will attack all players. Any dead players will come back with 1 HP after the battle has finished. The game will not end until all players have been defeated.

Characters

The sequel contains 5 characters. From the first game we have the Ironclad, Silent and Defect. We get two new characters; The Necrobinder is a Lich with a large skeletal hand called Osty which attacks and defends. The Regent is a cosmic king who creates a royal sword. He spends his new resource of stars to play more powerful cards. The Watcher is not included which was added in a free update to the original game.

Structure and meta-progression

Every act is now split into two different versions, which are randomly chosen during gameplay. Each version has unique enemies, story events and bosses. The game also includes a Timeline and Epoch system. This shows the history of the Spire and characters fighting against it and will allow you to unlock new characters and features when certain milestones have been achieved.

Technology and platforms

The original game was developed using libGDX, a Java framework that co-founder Casey Yano has expressed frustrations with due to crashing issues when updating operating systems, as well as the lack of console support. The sequel was initially developed in Unity, before switching over to use the Godot engine due to Unity’s controversial license changes in 2023. The Early Access build is currently available on PC (Windows, macOS, Linux) but there are currently no confirmed console/mobile releases.

Where the Original Still Leads

Completeness

Released from Early Access on January 23rd, 2019 Slay the Spire has an 89 Metacritic score on PC. It has a 98% recommendation rating from critics on OpenCritic. The sequel is still in Early Access. Mega Crit says the current version of the game is very complete but has some temporary art assets for new content. They have said it will be mostly focused on balancing. The Steam page says there will be more content added when it fully launches, a real ending, extra modes and better balancing.

Breadth of content and platforms

The game is available on PC, Nintendo Switch, PlayStation, Xbox One, iOS and Android. The game can be extended with an optional fourth act that can be unlocked by collecting three keys to fight the Heart of the Spire. There are twenty difficulty levels for ascension. You can also play a daily challenge with a set seed, a custom mode with modifiable modifiers and support for Steam Workshop.

Stability

While the Early Access phase has been plagued by balancing patches which caused review bombing, several strong cards were nerfed at release. This is all par for the course with Early Access but players looking for a stable game will appreciate the original version.

Which Game Should You Play?

The first game is a great choice if you’re new to deck builders as it’s complete, readily available, and well documented. If you’re a returning fan and enjoy tinkering, the sequel will offer some nice new characters and co-op gameplay. However, you do need to be okay with constant rebalancing. If you’re looking to play with your friends then there is only one option. Many will also opt to own both games.

Comparing Prices on Both Games

Both games list at $24.99 on Steam, so buying both at full price costs $49.98. Gamepriceradar is a price comparison website, not a store, and it does not sell game keys. It allows users to compare Steam key prices from different sellers and identify the best deal.

At the time of writing, in mid-November 2026, readers could compare Slay the Spire Steam key price and compare Slay the Spire 2 Steam key price on two separate pages, each showing Steam’s official price alongside offers from third-party key sellers. The older game showed the larger discount.

Game	Steam official price	Lowest key offer listed	Difference
Slay the Spire	$24.99	$6.61	$18.38
Slay the Spire 2	$24.99	$16.76	$8.23
Both games	$49.98	$23.37	$26.61

Each page also tracks price history. The Slay the Spire price history records an all-time low of $5.16 on October 23, while the Slay the Spire 2 price history shows Steam’s price holding at $24.99 as key offers declined from September. Because prices change frequently, readers should check the current Slay the Spire price and Slay the Spire 2 price before purchasing, and can set a price alert on either page to be notified of a drop. It's important to check the sellers' reputations. The listings will have region and edition noted. The pages will have information to make sure you're purchasing for the right activation region and edition.

Conclusion

Slay the Spire 2 is more of an expansion to the original. The original game is very complete, available on lots of platforms and has so many features. The second game adds co-op, new characters and increased variety between each playthrough but is still in the process of balancing and expanding. If you can only get one game I would recommend considering the stability of the first game. If you are able to get both games then comparing the prices will save you quite a bit.
