- Public Beta Test Postponement Notice - 3 July 2026
Hello, this is nemonan, the development team behind Frostrain 2.As mentioned in our previous developer letter, we had planned to hold the public beta test sometime this week. However, after conducting an internal test today, we found a number of bugs and areas that still require additional improvement.We have determined that, in its current state, the game would not provide a satisfactory testing environment for players. As a result, we have unfortunately decided to postpone the public beta test.Over the next week, we will be conducting intensive internal testing, addressing the bugs and issues we have found, and improving the overall quality of the game. We currently plan to proceed with the public test sometime next week.We sincerely apologize for the inconvenience to everyone who has been waiting. We will do our best to present the game in a better state.Sincerely, nemonan
- June Developer Letter - 30 June 2026
It feels like only yesterday that we were rushing to put out the May Developer Letter, but somehow, June is already coming to an end. Time really does fly. Half of 2026 has already passed. How is everyone doing with the goals you set for the new year? At this point, it feels like the long journey of Frostrain 2 is finally nearing its end. We expect to be able to present the full version to you sometime in July. And when that happens… this Developer Letter may very well be the last one!For reference, the public beta test for version 0.9.0 is scheduled to begin sometime this week. As with the previous public beta test for version 0.8.0, there may be many rough edges during the early stages of release. We plan to keep improving these areas through continued patches, so we hope many of you will participate!ProgressDo you remember the “-%” shown on the profile button on the title screen? Som…

- May Developer Letter - 27 May 2026
It’s May! How has everyone been? Here, it feels like summer has already come rushing in. It’s very hot… and humid. How are things where you are? I hope it’s more comfortable there.We were so busy with development that we completely forgot, but we ended up missing the April developer letter! Please accept our apologies for sharing this news belatedly like this. We have more or less wrapped up work on the Im Seokdae administration, and we are now developing the Jo Mimi scenario. Based on the previous Choi Soonja and Im Seokdae scenarios, we would like to try something a bit more experimental this time.RulerFrostrain is a game that is quite difficult to define by a single genre. It clearly has roguelike deckbuilding elements, but when you look closely at the game, it also has a strong strategic side. So this time, we wanted to further strengthen that “strategy game” aspect. Deckbuilding wi…

However, this approach had two issues. One was that it relied on probability, and the other was that it allowed for micro-control. The randomness was acceptable to some extent, but the micro-control needed t…
- 0.8.4 Update - 8 May 2026
While trying to update the game more frequently, I was reminded why the previous 0.7 version updates stopped at 0.7.4. When there is no new content… there are naturally fewer things to fix, aren’t there? It is obvious, but I have realized it once again. Since we are currently continuing to develop new content, this update only includes relatively small changes focused mainly on balance adjustments. Thank you for your understanding.BalanceSynergiesShadow Traders AssociationNow has 2 shop slots at synergy level 2, 4 shop slots at synergy level 4, and 7 shop slots at synergy level 6.Fuel and Hammer BrotherhoodFuel and Hammer Brotherhood (9): When producing Happiness, produce it 8 additional times. -> When producing Happiness, produce it 7 additional times.EntertainmentEntertainment (3): Gain 3x Happiness at a 33% chance and -6x Happiness at a 6% chance → Gain 2x Happiness at a 33% chance a…
- 0.8.3 Update - 23 April 2026
This update is primarily a breathing-room patch focused on balance adjustments, bug fixes, and small improvements.BalanceConductorsChoi SoonjaChoi Soonja became noticeably easier after the last patch. On the default difficulty, the win rate rose to the level we intended, but Extreme Cold also became too easy as a result. High difficulty should remain high difficulty. So we are making Extreme Cold harder again, closer to its previous level.Low Approval Ratings: Decision completion time +30%, Discontent +16% → Decision completion time +30%, Discontent +25%Irritable Passengers: Discontent +66% → Discontent +75%Im SeokdaeEndless Winter: Blizzard movement speed +5%, Discontent +25% → Blizzard movement speed +5%, Discontent +35%SynergiesShadow Traders AssociationShadow Traders Association (4): Gain 200% more Mileage → Gain 300% more Mileage.Shadow Traders Association (6): Gain 500% more Milea…
- 0.8.2 Update - 16 April 2026
This patch includes what we consider the “foundation” for rebalancing the difficulty gap between Choi Soon-ja and Im Seok-dae. We do not expect to solve everything in a single patch. We will continue correcting this balance through next week’s patch and the one after that.In addition, Perks are being added. From now on, if you purchase every artifact shown on a single shop page, you will unlock a Perk, making future journeys permanently easier to enjoy. We expect this to both create stronger incentives to buy artifacts and help offset the issue of “polluting” the pool whenever you make a purchase.Balance PatchConductorsIm Seok-dae’s win rate has been extremely polarized. Some players found him very difficult, while others found him too easy. According to the data, his win rate on Frost 3 was not very different from Choi Soon-ja’s, but his base difficulty was so much easier that there wa…
- 0.8.1 Update (New Language Supported!) - 8 April 2026
This update is focused on making Choi Sunja’s game easier to play and smoothing out Im Seokdae’s difficulty curve across the full run.Previously, the game may have felt as though it applied too much pressure too heavily in the late game, which could have made progression feel “unfair.” We want to alleviate that.This update includes a large number of changes, so there is a risk that we may not have tuned the difficulty perfectly. This update is by no means final or permanent, and depending on the data, we may make the game easier or harder through follow-up patches. So... we’d really appreciate lots of feedback!BalanceDecisionsChoi Sunja is getting buffed. It is time for this brilliant engineer from the academy to deliver an even better performance.Illicit Asset Recovery: Gain 1 Backlash, gain 3 Artifact Drone Supplies. → Gain 2 Backlash, gain 3 Artifact Drone Supplies.Deregulation: Lose…

- March Developer Letter - 31 March 2026
March is already coming to an end. This month, we were busy beta testing the new update, so this letter ended up arriving a bit later than usual. While we wait for the upcoming 0.8.1 update, I would like to briefly summarize what is coming.Our development team is, quite literally, “growing alongside the game.” We released Choi Sunja’s scenario to you through Early Access, and during that process there were many moments where we thought, “Ah, this would have been more fun if we had made it this way.” We took those lessons, refined them, and used them to make Im Seokdae’s scenario much richer. Of course, unlike Choi Sunja, Conductor Im Seokdae’s situation is focused less on “survival” and more on “rule.” Because of that, you may find the experience somewhat different.Domination, Transcendence, and ConsensusThe styles of rule presented by Im Seokdae can largely be divided into three paths.…

- 0.8.0 Preview - 13 March 2026
Hello! Today we wanted to reach out to those of you who might be wondering, “Why hasn’t there been an update for a month?” and feeling a bit anxious. We want to assure you that development is continuing every day, and we’re dedicating more than 13 hours a day purely to development. Today we’d like to share a bit about what’s being prepared for the upcoming 0.8.0 update.Im Seok dae and DecisionsIm Seok dae will be able to make decisions different from Choi Soon ja. Since the two conductors have different personalities, it wouldn’t make sense for them to share the exact same decisions. All of the materials shown here are still under development and may change at any time!In fact, in the previous developer letter we mentioned that we were trying to add decisions that would allow players to adjust the game’s difficulty themselves. However, that idea has been rolled back as well. We’ll conti…
