Slay the Spire 2 review: Four people can make this decision worse

The big picture

Slay the Spire 2 takes the delicate process of choosing the wrong card for excellent reasons and allows friends to participate. Mega Crit keeps the solo climb while adding online cooperative runs for up to four players. You can now discuss a risky strategy, hear objections, clarify your reasoning and make the questionable choice anyway. At least the disaster will have enjoyed a thorough introduction. Early Access launch

Developed and published by Mega Crit, the sequel launched into Steam Early Access on March 5, 2026, and remains there in the October 16 review snapshot. Its appeal is a fresh set of roguelike deckbuilding problems, with co-op changing who gets involved in solving them. The available game should be the reason to buy now. A future finished version is an intention, not a secret card you can currently draw.

More possibilities, same obligation to think

Enchantments, afflictions, Ancients and alternate acts join new events and enemies among the additions. They broaden the situations your deck must answer and create room for surprise after the original's problems have become familiar. Someone who enjoyed learning the first game has a clear reason to investigate another set of relationships. Developer FAQ

Still, a powerful collection of individual cards needn't form a useful deck. Adding a wonderful new option can make the tool you actually need harder to draw when it matters. Restraint therefore remains part of the appeal. Sometimes the sensible decision involves declining the exciting object, which is a deeply inconsiderate thing for a game full of exciting objects to ask.

The sequel doesn't promise a wholesale escape from its genre. Its case rests on giving deliberate experimentation new material. If roguelike deckbuilding itself has become tiring, more variations may not solve that. If you enjoy the central process and simply want unfamiliar problems, the additions have a much clearer purpose than the numeral alone.

The co-op matchmaking service is your friends list

Multiplayer works through Steam friends and has no matchmaking. Plan accordingly: this is a game-night option, not a guarantee of finding random companions whenever the urge to climb appears. The social arrangement is part of the purchase decision, especially if most of your friends respond to proposed activities with “maybe later” and then vanish into another game. Multiplayer FAQ

Team synergies change what makes a choice useful. Helping the group may matter more than immediately improving your own deck, opening room for coordinated plans and generously supporting someone else's combination. That also creates the possibility of one player enthusiastically managing every decision from a distance. Four-player co-op should ideally contain four participants, rather than one strategist and three people operating the approved buttons.

Agree on pace. A group that enjoys discussing options can find that conversation part of the evening, while players seeking rapid decisions may resent a lengthy debate over every card. Neither preference is inherently superior. Discovering the mismatch halfway through a run just gives everyone an additional problem the deck cannot solve.

Early Access still means unfinished

The Steam page lists additional content, a true ending, more modes, balancing and fixes among the plans for full release. Mega Crit estimates roughly one to two years in Early Access and says the price will rise afterward. The timeline remains an estimate, not a date you should circle as though the Spire has booked a venue. Early Access statement

September 25's Neowsletter discusses ongoing features, modes and improvements without dating the next patch. If a particular future addition is essential to your interest, wait until it exists. Buying an evolving deckbuilder also means accepting that balance changes may rearrange a favorite strategy. Some players enjoy having fresh reasons to rethink their habits. Others would prefer the rules to stop moving while they're trying to learn them. September update

Pick your device and your moment

Native Windows, macOS and Linux releases are confirmed, with macOS 12 or later listed. Valve rates Steam Deck Verified, and Mega Crit confirms compatibility. Native console and mobile releases remain future intentions. Newcomers don't need to finish the original before starting this one, so there is no compulsory preliminary climb before being allowed to make fresh mistakes. Platforms and entry requirements, Deck report

GeForce NOW offers a separate streaming route to the Steam PC game on supported devices, including qualifying mobile devices, Chromebooks and headsets. Steam ownership, a GeForce NOW account, suitable controls, supported region and connection requirements apply. Headsets display the game in 2D cinema mode with a separate gamepad; they don't turn it into a native VR adventure. Cloud catalogue, Device requirements

Slay the Spire 2 suits players ready for new strategic experiments now, particularly with friends who share their pace. Wait if a finished ending and settled balance matter more. Either decision is defensible, which should provide useful practice for an evening spent staring at three cards and confidently explaining why all of them are a terrible idea.
