Mega Crit co-founder Casey Yano confirmed in a Kotaku interview that Slay the Spire 2 will add new playable characters beyond the five launch roster slots and three entirely new game modes aimed at competitive, short-session, and social players.
In an April 2026 interview with Kotaku, Mega Crit co-founder Casey Yano confirmed two roadmap items for Slay the Spire 2: at least one additional playable character beyond the five in Early Access, and three distinct new game modes layered on top of the base campaign.
Yano framed the new characters as coming after an internal experimentation phase. He noted that launch-era characters like Regent (dual-resource Stars + Forge) were designed to be mechanically simple, while Necrobinder (Doom + Souls + Osty companion) already pushes further into complexity. Future characters will likely fall somewhere on that spectrum.
The three modes are described only in broad strokes: a competitive mode, a short-session mode for players without time to commit to a full run, and a social / multiplayer-adjacent mode that goes beyond the existing 4-player co-op.

Yano's exact framing is that Mega Crit wants to try new character ideas but they need to pass the internal experimentation phase first. He didn't commit to a number or a date, and he explicitly said it's unclear whether every experiment will be released publicly.
Reading between the lines: the launch five (Ironclad, Silent, Defect, Necrobinder, Regent) were the characters that cleared the bar. Anything added later will be tested against that standard and may get cut if it doesn't work. The Watcher fan-favorite request from STS1 fits this pattern — she's absent from the launch roster, which suggests Mega Crit is waiting on a stronger mechanical identity for her before committing.
Yano described three concrete mode ideas he's been developing. The descriptions are deliberately vague to avoid pre-announcing features, but the three buckets are clear.
Mode 1 is competitive: a format aimed at players who want measured matchups against other humans. This is separate from the existing co-op (which is cooperative up to 4 players). Daily Climb from STS1 was the closest analog — expect something more structured.
Mega Crit launched Slay the Spire 2 on March 5, 2026 at $24.99 into Early Access. Yano's roadmap comments confirm that EA is not feature-complete — characters and modes beyond the March 5 build are still in the pipeline.
The first beta patch (v0.102.0, April 10, 2026) already delivered Ironclad rebalancing, Act 2 encounter changes, and new cards like Not Yet. That set a cadence of roughly monthly balance patches. New characters and modes are a separate, longer-horizon track and should not be expected in every patch.
The most obvious question: when will Watcher, the fan-favorite from STS1, return? Yano didn't name her directly, but his 'experimentation phase' language implies that any returning STS1 character has to pass the same bar as a new one.
Watcher's defining mechanic (Wrath + Divinity stances) would need to be rebalanced for STS2's new resource systems (Stars, Forge, Doom, Souls), and Mega Crit has publicly said they don't want to ship a character that plays identically to the STS1 version. Expect her to appear only once the team has a version that uses sequel-specific hooks (possibly Enchantments, Ancients, or Alternate Acts biomes).
The v0.102.0 beta patch on April 10, 2026 gives us an early read on how Mega Crit sequences content. Balance changes (card nerfs, elite rebalances, Affliction tweaks) ship first; net-new content (modes, characters) comes in bigger batches.
If STS1 Early Access is a template, expect one major content drop every 3-4 months during STS2's EA — new characters in those drops, new modes potentially tied to them. Casey Yano's 'experimentation phase' suggests he wants multiple prototypes tested internally before anything ships, so don't expect new characters in the first several patches.
FAQ
Yano used the phrasing 'new character (or multiple characters)' in the Kotaku interview, committing only to at least one. He deliberately did not give a number because content still has to clear Mega Crit's internal experimentation phase before it's promised publicly. The launch five — Ironclad, Silent, Defect, Necrobinder, Regent — will be joined by at least one more, with no announced date.
A competitive mode for players who want head-to-head or ranked play, a short-session mode for players who can't commit to a full 60-120 minute run, and a social / multiplayer-adjacent mode that builds on the existing 1-4 player co-op. Yano described them in broad strokes only and admitted he wanted to be vague so Mega Crit could change course during prototyping.
Mega Crit has not announced dates. Based on STS1's Early Access cadence (18-month EA, major content every 3-4 months), expect the first new character no sooner than late 2026 and the first new mode around the same window. Yano's experimentation phase language suggests content may slip if prototypes don't hit Mega Crit's internal bar.
Not confirmed. Yano didn't name Watcher directly, but his 'future characters' comment leaves the door open. The design constraint is that every STS2 character must have a mechanic the others don't — Watcher's Wrath/Divinity stances would need reworking to avoid overlap with Regent's Stars resource and Retain keyword. Expect Mega Crit to either ship a reworked Watcher or skip her in favor of sequel-native characters.
Both, on different cadences. Balance patches like v0.102.0 (April 10, 2026) ship roughly monthly and tune existing cards, bosses, and Afflictions. New characters and new modes are a separate, longer-horizon track that Yano described as gated by internal experimentation. Mega Crit has not said they'll pause content for pure polish — the April patch did both simultaneously.
The launch build has 5 characters, 3 acts, co-op up to 4 players, Enchantments, Quest Cards, Afflictions, Alternate Acts biomes, and Ancients blessings — the scope is already larger than STS1 at 1.0. Steam reviews sit at 97% positive. Buying now gets you balance patches and eventual free content updates. If you want the full roster before committing, wait for Mega Crit's 1.0 announcement, which based on STS1 history is likely 12-18 months out from launch.
