Official Frostrail demo graphic: next fest demo content, explore 3 areas, conduct your train, scavenge and craft, fight revenants

You are one of the Penitent Gardeners, crewing an armoured steam locomotive through the ruins of a frozen empire: scavenging what the frost left behind, feeding the boiler, and fighting what the Emperor's pact with the Void brought back. FakeFish — the Finnish studio behind Barotrauma — is building it in Unreal Engine 5 for PC, with Early Access planned for 2026 and co-op for one to four players.

Written against the build you can play: the Next Fest demo live since 19 October 2026 (app 5090080), plus official announcements to the same date.

What the demo actually contains

The official demo graphic lists four verbs, and they are an accurate summary of the loop: explore 3 areas, conduct your train, scavenge and craft, fight revenants. One locomotive, three areas, settlements to strip, stations that turn scrap into gear, and Revenants that hunt you the moment you leave the heated cabins.

It runs during Steam Next Fest from 19 to 26 October 2026 and is free — you install the separate Frostrail Demo app, not the full game. Languages: English, French, German, Portuguese (Brazilian), Russian, Spanish, Simplified Chinese.

How to read this site

Start with the demo page for install and dates, then gameplay for the loop and survival before your second run. Weighing a purchase? What Frostrail is, co-op and system requirements — the recommended GPU is an RTX 4060. Counting days? Release date and price.

What this site will not do

No codes: Frostrail has no code system, no redeem field, and no key entry anywhere. No tier lists either — ranking weapons off a three-area slice of an unfinished build would be a guess dressed up as data.
