About Frostrail

Frostrail is a dieselpunk open-world survival-crafting FPS for one to four players, developed by FakeFish and published by Shiro Unlimited in Unreal Engine 5.

Early Access planned Q4 2026

What kind of game is Frostrail?

Frostrail combines first-person combat, open-world survival crafting, exploration, base building, horror, inventory management, and resource management. Its defining base is an armored train called the Eden Engine.

  • Single-player and online co-op
  • Frozen level exploration
  • Craftable and modular firearms
  • Train operation, expansion, and defense
  • Cold, heat, food, clothing, Relics, and dungeons

Developer & publisher

FakeFish is a Turku, Finland studio founded in 2014 by five university friends. Publisher press kits describe an independent studio of about 30 people whose first game, Barotrauma, has sold more than three million units since 2019. Many Frostrail developers previously worked on Barotrauma; a Gamescom founder interview said around 15 people were working on Frostrail at that time. Shiro Unlimited, the publishing label of Shiro Games, is the publisher. Steam lists support@shirogames.com.

Setting & story premise

The former empire was frozen after its Emperor made a pact with the Void. Players are Penitent Gardeners traveling north aboard the Eden Engine, scavenging abandoned settlements, wreckage, ruins, bunkers, strongholds, and dungeons while fighting Revenants and eldritch horrors.

What the game is built around

Every part of a run comes back to five ideas: the moving train base, ranged combat, lethal cold, co-op, and turning scavenged materials into something useful. The Eden Engine is not scenery—it sets how far the crew can explore, what can be carried home, and whether the journey continues.

World & progression structure

The journey moves north through separate levels. At the end of a level, the crew uses a tunnel to select the next route; the world becomes colder and harder farther north. Terrain is hand-made, while natural assets, selected point-of-interest placement, loot, and enemy spawns use procedural systems for replayability.

The May 2026 update says progression now carries between levels and that new levels can provide multiple exits.

Languages, ratings & Steam features

The current Steam store lists interface and subtitles in English, French, German, Spanish (Spain), Portuguese (Brazil), Russian, and Simplified Chinese, with no full-audio language. Publisher press kits for the 2026 playtest and Closed Beta also name Polish for Early Access, although Polish is not yet on the live Steam language list.

Steam currently lists single-player, multiplayer, online co-op, achievements, and Family Sharing. The mature-content note mentions combat against wolves and humanoid creatures with blood splatters.

The October Next Fest demo graphic separately lists seven languages, including Simplified Chinese. This confirms announced demo language coverage; it does not describe the settings menu or add full-audio support.

How this wiki is written

Frostrail Wiki is an independent fan project, not a FakeFish or Shiro Unlimited website. Pages are written to answer player questions first, then show the date and links used to check details that may change during development.

The site does not claim hands-on experience with a build unless a page names the test and the experience actually took place. Store pages, game builds, development posts, screenshots, and named interviews are kept separate so planned features do not read like finished mechanics.

  • No invented damage, drop-rate, recipe, or performance values
  • Build-specific numbers keep their date or test context
  • Placeholder retailer dates are not treated as release dates
  • Substantial updates change the page date; cosmetic edits do not

Corrections & contact

Frostrail is changing quickly, and a test build can make an older detail obsolete. If you spot a wrong date, mislabeled screenshot, broken link, or value that changed in a newer build, use the Contact Us link in the footer and include the page URL plus a screenshot or public announcement when possible.
