Hello to all the conductors around the world enjoying the Frostrain 2 demo!
As mentioned previously, Frostrain 2 is still in its demo phase and far from polished. We’ll continue adjusting balance and improving any uncomfortable parts. Looks like we’ll be meeting quite often this week!
This patch includes the following changes:
Balance Adjustments
[6] Central Supply Bureau synergy effect: Cycle reduction changed from 6 seconds → 5 seconds.
→ The Bureau was excelling both in versatility and sheer power — too much for the others to handle. We’re slightly reducing its effect to observe how things settle.
[5] Entertainment synergy effect: 77% chance to produce 10× Happiness → rolled back to 77% chance to produce 7× Happiness.
→ The average Happiness output of Cryptography Room, Geoinformation Office, Training Center, and Entertainment Management Division increased by 30%.
→ Our intent to slightly buff Entertainment synergy made it far too strong! We’re keeping the “77–7” concept but toning it down. This change also helps the somewhat underperforming Academy while softening the impact of the Central Supply Bureau’s nerf.
[3–5] Media synergy effects: adjusted as follows
3 Media: +20 → +16
4 Media: +50 → +36
5 Media: +128 → +88
→ Despite requiring relatively few trains, Media synergy maintained an extremely high win rate — especially with Conductor Choi Sun-ja’s traits. Since the demo currently only allows her as the playable conductor, we’re scaling down its power to improve overall balance.
Shadow Traders Association trains gain a new ability:
“Each time you restock shop items, produce +1% more Happiness.”
(Tier-4 Cartel trains gain +2% instead.)
Shadow Traders Association shop item appearance rates adjusted by level.
→ The faction excels at repeated rerolls to build up early and midgame, but lacked late-game incentive. We hope this change will make their ‘shopping’ payoff more satisfying.
Artifact – Power Cycle Amplifier: maximum cap reduced to +416.
→ Far too many of you have pierced the heavens with this one... We admit, that’s on us.
To ensure more balanced choices in the Poverty Relief Policy event, the following adjustments have been made:
Power Diversion artifact effect: Movement Speed −12% → −8%
Im Seok-dae – Passenger Execution option has been adjusted and expanded as follows:
Passenger Execution: 3 → 2
Rebellion gained: 2 → 1
Population Density lost
Im Seok-dae – Accept Poor Car option now grants an additional effect:
Gameplay Changes
Train colors slightly adjusted.
→ Our last change for visibility ended up being too harsh; we’ve fine-tuned saturation and tone.
Maximum upgrade tiers are now visually indicated on cards.
→ The dimmed gem icons represent the train’s upgrade cap.
Synergy tooltips now list which trains belong to that synergy.
Event “Unsettled Atmosphere” now features heartbeats and tunnel-vision effects when triggered.
Artifact “Repulsion” tooltip now correctly displays both initial and current values.
Inventory synergy tooltip delay increased from 0.2 s → 1.2 s.
→ Prevents tooltips from obstructing the screen when hovering over the inventory.
Story events now display a story badge, clearly distinguishing mandatory story events from optional random ones.
Happiness production by trains is now visually more noticeable.
Drone supply option spacing adjusted for improved readability when options expand or shrink.
Bug Fixes
Fixed: “Unsettled Atmosphere” event heartbeat sound not playing properly after saving/loading.
Fixed: Tier-4 Cartel train’s pivot being slightly misaligned.
A problem where certain trains (Field Kitchen, Wheel House, GeoGraphic Information Office, Cartel) appeared unusually rarely has been fixed.
Ongoing Work
Apologies — the following fixes are still in progress:
Rare issue where some trains fail to display tooltips.
A tutorial overhaul is underway. It’ll take some time, but expect a much friendlier and clearer experience soon!
We’re also preparing an update before the October Steam Next Fest (Oct 13) to add five additional language supports:
Japanese
Greek
German
Simplified Chinese
Thank you for riding with us!
