Slay the Spire 2: New Necrobinder Class, 2025 Release & Overhaul

Last Updated: October 23, 2025

Mega Crit has officially broken its silence, confirming the highly anticipated Slay the Spire 2 will enter Early Access in 2025. The announcement, which electrified the gaming community during the Triple-i Initiative showcase, came with a gameplay trailer that gave fans their first look at the sequel's evolution, including a brand-new playable character: The Necrobinder.

This definitive 2025 launch window replaces all previous speculation about the sequel's arrival. Forget rumors of distant dates; the ascent begins next year. The reveal trailer showcases a game that is both familiar and fundamentally new, built from the ground up in a new engine and loaded with features that promise to make the return trip to the Spire even more compelling than the first.

A New Challenger Appears: Meet The Necrobinder

Headlining the reveal is the introduction of the first new playable character, The Necrobinder. This death-defying spellcaster brings an entirely new archetype to the Spire. Clad in ominous purple robes and wielding a sentient, cursed book, The Necrobinder’s gameplay appears to revolve around forbidden magic and reanimating the dead.

While Mega Crit is still holding the full deck of details close to its chest, the trailer hints at powerful necromancy skills that will offer a fresh strategic layer for veterans and newcomers alike. The Necrobinder joins the returning iconic trio—the Ironclad, the Silent, and the Defect—ensuring the initial character roster is both deep and diverse right from the start of Early Access.

A Modern Foundation: New Engine and Mod Support

One of the most significant upgrades for Slay the Spire 2 is the complete engine overhaul. Mega Crit has rebuilt the game from scratch using the modern, flexible Godot engine. This move isn't just a behind-the-scenes technical change; it promises a more polished experience, smoother performance, and greater potential for complex visual effects and animations.

Crucially, this new foundation was built with the community in mind. Mega Crit has confirmed that Slay the Spire 2 will feature robust mod support from day one of its Early Access launch. Given the original game's legendary modding scene, which produced countless new characters, relics, and even full-scale expansions, this commitment is a massive win for the community and ensures the sequel will have a virtually endless lifespan.

The Early Access Philosophy Returns

Following the wildly successful development path of the original, Slay the Spire 2 will once again utilize an Early Access model. This approach allows Mega Crit to build, balance, and refine the game alongside its most dedicated players. Fans can expect an iterative development process where their feedback directly shapes the final product, from card balance to new event design.

The 2025 Early Access launch will provide the core experience, allowing players to climb the Spire with the initial cast of characters. Over the following months, Mega Crit will expand the game with regular updates, adding new cards, relics, events, and secrets, just as they did for the genre-defining original.

Looking Ahead: The Climb to 2025

While the wait for Slay the Spire 2 continues, the official reveal has replaced years of speculation with concrete, exciting facts. The sequel is not just more of the same; it's a comprehensive evolution. With at least one new slayer in The Necrobinder, a powerful new engine, and a foundational commitment to its modding community, Slay the Spire 2 is poised to reclaim its throne. The Spire is calling once more, and the ascent is scheduled for 2025.
