What Frostrail actually is

Frostrail steam train rolling past ruined snow-covered cabins on a frozen tundra

Frostrail is an upcoming Unreal Engine 5 survival FPS from FakeFish, the studio behind Barotrauma, published by Shiro Unlimited. You ride a steam-powered train across a frozen empire, fuel the Eden Engine, scavenge ruins, and fight Revenants solo or in online co-op for crews of 1–4. Early Access is planned for Q4 2026 on Steam. Start with the Getting Started guide, learn the core loop, then check closed beta access and the weapon tier list.

Quick start

Five steps from wishlist to a useful closed-beta session.

  1. 1

    Wishlist and follow the Steam page

    Wishlist Frostrail on Steam so you catch Early Access and playtest waves. Official PC specs are still TBA — bookmark the system requirements page.

  2. 2

    Request closed-beta access

    Use Request Access on Steam. Prior playtesters stay in the pool. If a friend is already in, they can send invites from the store page — see how the closed beta works.

  3. 3

    Learn the first-hour loop

    Tutorial, fuel the Eden Engine, scavenge a stop, fight the walk home. The Getting Started guide and how to play cover that loop without dumping endgame theory.

  4. 4

    Assign crew jobs before you leave the train

    Online co-op supports up to four. Split engine, loot, and rear security using the co-op guide and the survival checklist.

  5. 5

    Send feedback FakeFish can actually use

    Beta has no NDA. Use the in-game bug button, the survey, Steam Playtest discussions, and Discord testing-corps. Track bigger shifts on the roadmap.

FAQ

Wiki FAQ

Quick answers to the most common questions.

When does Frostrail come out?

Early Access is planned for Q4 2026 on Steam for Windows PC. FakeFish expects roughly a year in Early Access. There is no 1.0 date yet. Follow updates when windows move.

How do I join the closed beta?

Request access on the Steam page. Anyone who signed up for an earlier playtest is already considered. Accepted players can invite up to three Steam friends, and those friends can invite three more. Full steps live on closed beta.

Is Frostrail single-player or co-op?

Both. The game is built for crews of 1–4 with online co-op. You can run the pilgrimage solo. Local split-screen is not the advertised mode. See how to play and co-op.

What is the Eden Engine?

The life-support heart of your steam train. You fuel it, manage power, and upgrade it so the convoy can push farther into the frost. The train guide explains why leaving it cold is a run-ender.

Which languages does this wiki cover?

English, French, German, and Spanish. Steam also lists Brazilian Portuguese, Russian, and Simplified Chinese; this wiki skips those last two by design and did not add a fifth locale.

Are the weapon ranks final?

No. Lists on this wiki are built from official interviews, trailers, and playtest footage. Early Access will reshuffle guns and Relics. Treat the weapon tier list as a starting map, not a patch bible.

Ready to board the train?

Use the Getting Started guide for your first hour, the closed beta page for invites, and the survival checklist before you leave the rails.
