Hi everyone, this is Casey! Slay the Spire 2 has been out for about a month. As a strategic card game + roguelike tower-climbing experience, we have been focusing on polishing the core gameplay loop: you play as an adventurer who builds custom card decks, collects powerful relics, and battles monsters in procedurally generated spires — every run feels fresh and unique.

Our recent work has centered on** fixing critical issues, improving in-game feedback systems, refining visual presentation, and reworking and balancing cards and items**, to ensure every card and piece of equipment offers distinct fun and viable strategic value.

A huge thank you to everyone who has sent in feedback! Just a reminder: the in-game feedback tool provides us with far more structured data than emails or social media posts (fun as those may be).

The road to Version 1.0 is still long, but as we enter the warmer months, we aim to shift focus toward larger content updates. Since our Early Access disclaimer is fairly vague, we wanted to share a more official and up-to-date roadmap.

Core Gameplay Introduction

Slay the Spire 2 builds on the classic deckbuilding roguelike formula of the original with major mechanical upgrades:

Deck Construction

Unlock hundreds of unique cards and combine attacks, defenses, and skills to create your ideal playstyle.

Procedural Climbing

Levels, events, enemies, and rewards are fully randomized — no two runs are the same. Relics & Potions

Collect game-changing relics and use potions to turn the tide of battle, deepening strategic depth.

Dynamic Events

Encounter random story events where your choices lead to rewards, risks, and surprises.

  • “True Victory” and all associated content

You might be wondering: where are the dates? Why no firm deadlines?

My answer is simple: it doesn’t work for our team.

Mega Crit is a small studio where every member knows their role and each other. I do my best to keep us working at a healthy, sustainable pace. We evaluate priorities weekly and focus on what matters most. This approach isn’t the most structured, but it lets us experiment freely — leading to creative moments like conversations with The Ancients or the iconic Room Full of Cheese. We will not drastically expand the team just to rush the game. Strict deadlines lead to sloppy, uninspired work. I don’t want Sloppy Spire 2. I want Slay the Spire 2.

While we don’t share strict timelines, beta patches release much more frequently than main branch updates. The beta branch is an optional version of the game for testing experimental changes. If you want to try new content early and share feedback, follow the instructions to switch branches.

Hi, this is Demi with some Slay the Spire 2 stats! Over a month since launch, you’ve completed roughly 145 million runs! Let’s dive into player choices during some iconic events:

Lantern Key in the Hive: 56% return it to the Mysterious Knight for gold; 44% fight to keep it. War Historian Repy: 88% free him for a valuable tome; only 12% abandon him for relics and potions.

Byrdonis Nest: 51% take the egg to hatch a Byrdpip companion; 49% eat the egg for extra max HP — nearly a 50/50 split!

Next time, we’ll explore more behind-the-scenes metrics!

Q&A with C&A

Q: Why do newsletters and updates always come out on Thursdays?

Casey: If we release earlier in the week, we have to monitor feedback nonstop. If issues or typos pop up, we can fix them on Fridays.

Q: Will you add multiplayer matchmaking or in-game chat?

Casey: Matchmaking is still uncertain. Random matchmaking brings challenges a small team isn’t ready to handle. We may add text chat, but likely not voice — unless something happens to Discord.

Q: Will you add an endless mode?

Casey: Probably not. Deckbuilding becomes less exciting over very long runs. Games like Balatro handle infinite scaling better. Still, inspiration is unpredictable — maybe a modder will make it work!

Q: Will you make an official Tabletop Simulator expansion for the board game?

Demi: Contention Games handles the board game. The Downfall expansion is now in public playtesting on Tabletop Simulator. The base board game is also available there. Join their Discord for feedback and teammates.

Q: Will beta patches come to the main branch soon?

Casey: Once the first balance patch feels stable. We may push some bugfixes to main even sooner — possibly before this newsletter goes live!

Questions from LEVEL 0 (Korean student game dev club)

Q: What was one non-negotiable for fun during development?

Casey: There must be whimsy.

Q: How did you keep team morale during long development?

Casey: Check in on the team’s spirit. If people only talk about tasks, take a break! We meet in person a few times a year. For game jams? Take a longer lunch and eat fried chicken. I love fried chicken. Also — I’m going to Berlin in May. Don’t tell anyone.

Q: A message for students in the Daegyeong Jam?

Casey: Remember to have fun! Don’t just eat protein bars and instant ramen! Merch Madness

Map Masterpieces

Last month we asked for your in-game map art — and we received way more than we could feature! Here are some highlights. To be featured next month, post in our Discord or send to fanmail@megacrit.com!

Would you like me to shorten this English version for social media or adjust the tone to sound more casual?
